Hex Editor with File Structure Viewer, NTFS Streams Support

Version 5.10

This release adds support for localization. Language packs are created as part of open source project and will be available through built-in updater once they are finished.

The first available language pack is Russian.

Besides, this release fixes a number of reported bugs. Please consult the View Changes page for detailed information.

Version 5.01

Major update to Structure Viewer

This version has completely new Structure Viewer, with a lot of new functionality and improvements. See the What's New in Structure Viewer (version 5.01) topic for more information.

Parallel operations

Several operations, like Find All and Replace All, now utilize several cores or processors (if they are available). It does not give linear speed-up, but sometimes up to 30% performance gain is obtained. Performance gain is more noticeable in Replace All commands, especially in regular expression mode.

True parallel execution of all lengthy operations

Previous versions allowed you to execute multiple operations in parallel, but user interface was rather limited: for example, it did not allow you to finish the first operation before the second finishes. Now, all started operations are equal and are executed truly in parallel. Application user interface is not blocked. Only windows of the current document are disabled until the operation execution is completed.

Support for Intel HEX and Motorola S files

Advanced Copy & Export now allows exporting selection into Intel HEX and Motorola S formats. In addition, new commands, File » Open » Open Hex… and Edit » Insert Hex… allow the user to convert Intel HEX and Motorola S files to binary form and insert them into the Hex Editor Neo.

Additional information is displayed for several lengthy operations

For Find All, Replace All and other operations, the number of occurrences found so far is displayed on the progress dialog.

Completely rewritten Checksum module

Checksum module has undergone complete rewrite, featuring new algorithms, greatly improved performance and parallel execution. That is, when several algorithms are selected at once, Hex Editor Neo utilizes multiple cores or processors (if they are available) to execute them in parallel.

More hash algorithms are offered (the actual list depends on algorithms available through Cryptography API). More different ways to sum all values in a document or selection are offered, including signed and unsigned sums.

User interface for a Checksum module has also been improved.

Ability to copy/export the current selection

Hex Editor Neo now allows you to get the list of selected ranges into the Clipboard or directly to text file.

Improved experience when opening volumes and disks

Hex Editor Neo is now capable of opening volumes and disks in the same running instance, even if it runs under non-privileged user account.

Goto Navigation panel

Each editor window has its own navigation panel with individual location history.

Improved setup speed

Speed of Hex Editor Neo setup application has been greatly improved. Installer now needs to update less files and system settings and operates much quicker.

Improved application start-up time

We have improved the applicaiton start-up time by reducing time required by various components to initialize and allowing several components to initialize in parallel.

Improved Find in Files/Replace in Files commands.

New version provides better utilization of multiple cores as well as proper operation on single-core computers; smoother operation on SSDs.

Improved support for eastern languages

Hex Editor Neo now provides better visual output of eastern languages characters in text pane.

Version 4.97

Support for Using Regular Expressions in Replace Pattern

Replace and Replace All commands now support regular expressions as replace patterns, allowing you to refer to parts of matched expression when performing a replace.

Support for Encodings in all Commands that Work with Regular Expressions

Find, Find All, Replace, Replace All, Find in Files, Replace in Files, Pattern Statistics - all these commands now fully support currently selected encoding when they work in regular expressions mode.

New scripting methods

The following new methods are available in IFileDocument:

Version 4.96

Integration with Windows Error Reporting

Hex Editor Neo now fully integrates with Windows Error Reporting. We will be able to receive each submitted crash or hang report, analyze it and provide a solution to the customer.

New Data Operations – Reverse Bits and Byte Swap

New Reverse Operations commands were implemented in this release. Use the first command to reverse the order of bits in each value in a selection and use the second command to reverse the order of bytes.

New Arithmetic Operations – Set Minimum and Set Maximum

Two new arithmetic operations allow you to limit each value in a selection.

Regular Expression Scheme Association

Structure Viewer now uses regular expressions to match a scheme with a the document.

Improvements in the editor

Various small bug fixes and minor improvements in the editor:

Application now remembers the state of the Details Selection tab between launches.
Keyboard focus is now moved into the opened document.
Shift+Home and Ctrl+Shift+Home keyboard combinations now correctly update selection.
Insert Mode can now be switched during editing.

Several Bug Fixes

Several reported bugs were fixed in Structure Viewer (see What's New in Structure Viewer (version 4.96) for more information) and Disassembler. In addition, reported errors in exporting selected data as Delphi array were fixed.

Version 4.95

UTF-8 Support

This release finally adds the UTF-8 to a list of supported encodings. Now it is not only supported in the Advanced Copy & Export module, but also in editor windows, Structure Viewer and everywhere else.

Hex Editor Neo supports single-byte, two-byte, three-byte and four-byte UTF-8 characters. Please note, however, that Hex Editor Neo has limited support for UTF-16 surrogate pairs.

See more information on UTF-8 support in the Encodings section.

Encodings in Structure Viewer

This release covers the last "hole" in encoding support in Hex Editor Neo - now Structure Viewer also uses the code page of the current editor window when it displays single-byte character arrays or strings.

Pasting Encoded Text

In this release, Hex Editor Neo also uses the current encoding when pasting text into the Text Pane of the current editor window.

Bug fixes

Several bugs were fixed in the Structure Viewer.

Version 4.94

This release introduces several bug fixes and a few improvements to various product functions:

Ability to specify the proxy server to use. Configured proxy server will be automatically used by such features as Check for Updates, Downloader and Crash Dump Uploader.
An additional column is added to the Open Disk dialog. It displays the physical drive information in a form of "\\.\PHYSICALDRIVEN", where N is a disk ordinal number assigned by operating system. This allows you to distinguish between the same disks from the same manufacturer.
All operations (bitwise, arithmetic and shift) dialogs now include the option "Whole File". You can use it to target an operation to a whole file without the need to select it first.
Current bookmarks are now displayed in the Go to Offset dialog.
Added an ability to manipulate the current selection directly from Go to Offset dialog. You can replace, add, remove or invert the current selection while changing the cursor offset in the document.

Portable Installations Improvements

Before this version, when you use the Hex Editor Neo in portable installation, it still uses the target system's registry and file system to store configuration data as well as temporary files.

Version 4.94 of the editor has been modified the following way:

On startup, Hex Editor Neo creates a key in the registry and imports the configuration data from portable.config file (located in the product startup folder).
On exit, Hex Editor Neo saves the configuration data back to this file and removes the registry key.

In addition, Hex Editor Neo stores vector image cache (used to decrease start-up time) in the user's profile temporary folder. You can switch off this behavior in the Tools » Settings…, General Tab.

Version 4.93

This release fixes a number of Structure Viewer bugs and further improves structure binding performance.

Here is a list of all changes in this release:

New tool window layout "Structure Analysis" provides maximum working space for analysing the document's structure.
TGA file structure is updated to support run-length encoded images.
Changed the displayed type name for bit fields. It now shows the number of bits a field occupies (for example: int: 4).
More accurate structure binding progress update. In addition, a progress window may switch to the marquee mode when binding complex structure with forward and backward pointers.
A bug that prevented bit fields from being indexed is fixed. Now when you click on the cell which contains a bit field in the editor, the field is properly highlighted in Structure Viewer.
The execution of the assignment statement (variable = expr;) is greatly optimized. Such complex iterative structures as AVI, TGA and others will benefit from this optimization.
Structure Viewer now displays a single common progress when binding a structure that executes delayed binds (like PE header, for example).
Structure Viewer tool window's main operations, like navigation, expanding/collapsing, scrolling and so on were optimized.

Version 4.92

General Bug Fixes

Sometimes when “Compare Files” command was launched as Windows 7 task from the pinned application icon, it crashed after you pressed the OK button.
Hex Editor Neo’s patch files were incorrectly registered by setup.

General

Hex Editor Neo now prevents the computer from going to sleep (unattended) when performing lengthy operation. This of course does not prevent the user to manually sleep the computer.
Now there is an option to move the cursor to the end of the pasted data after the Paste operation (turned on by default).
Now it is much more easier to select data with mouse. The behavior is more consistent with other Windows applications.
All Hex Editor Neo commands (such as Edit » Fill…, Edit » Find…, Edit » Replace… etc) now respect the current window’s encoding, when single-byte string type is chosen. The current encoding is also displayed in the command’s dialog. Note: when using regular expressions, default system encoding is always used.
Current editor window's encoding is also respected by Pattern Coloring module.
Mouse wheel scrolling now correctly works with high-definition mice.

Structure Viewer

Bug Fixes

Incorrect scope resolution for complex array indices.
Empty structures incorrectly had zero alignment, breaking any structure that referenced them.
Hex Editor Neo could crash when expanding string or wstring values.
When a script file referenced by a structure definition file was modified, Hex Editor Neo did not refreshed it properly, although notified the user of the change.
Enumeration visualization could produce incorrect results, if you used signed values in an unsigned enum.
Structure Viewer tool window could incorrectly display vertical lines.

New features

New statements: while, for and do…while.
$print directive now does not automatically convert its argument to string; instead it uses Structure Viewer’s data visualization engine. This allows it, for example, to respect the “Display Hex Values” setting when displaying integer values.
For pointed types, not only the pointer value, but the snapshot of pointed type contents is visualized on a line (as it is for arrays and structures). In addition, a computed address is also displayed.
Javascript code now may be specified inline with a new javascript keyword. Note that VBScript code must still be referenced with #pragma script directive.
Structure Viewer now uses the current editor window's encoding when displaying non-Unicode strings.
PE header sample has been greatly enhanced. Now it parses more PE file structures, including import and export directory, resource directory, base relocation table, debug directory and others. It also illustrates how to use Javascript to extend the power of Structure Viewer's declaration syntax.

Checksum

Click-and-calculate feature implemented: non-computed checksum value is automatically computed when you double-click it (no need to click checkbox and then Refresh)

File Compare

File Compare tool window’s commands are now application-wide commands. You can put them on the toolbar or assign keyboard shortcuts to them.

Clipboard

Now Edit » Copy and Edit » Cut commands automatically put selected data in text format into the Clipboard. Copy & Export tool window is still used to fine-tune the format used.
“Formatted Values” copy&export mode now allows exporting data without separators (as text stream).
“Raw Text” copy&export mode also lists “Current Encoding” as encoding type. When selected (default), encoding from the current editor window is used.

Version 4.91

This version features a completely rewritten setup for Hex Editor Neo.

Transactional Installation

Setup now performs installation of the product as a single transaction (on supported operating systems and configurations, see below). If anything goes wrong during installation, including software or hardware errors, computer configuration is not modified. All setup activities are part of the transaction, including modifications done to the file system and system registry.

Setup always tries to use transactions on supported operating system. If installation fails due to the transaction error, it retries the operation without using transactions. It also does not use transactions on legacy operating systems.

Requirements

Transactions are supported on Windows Vista or later operating systems. In addition, the product must be installed on the local NTFS volume.

Restart Manager Support

Now, when setup needs to replace or remove a locked file, it uses the system restart manager (Windows Vista or later) to find the application that has a file open. It also offers a way to gracefully restart the application in order to update the file. This new feature greatly reduces the need for system restart during setup.

On legacy operating systems setup emulates the restart manager's behaviour, still trying to minimize the need to restart a computer.

Per-User Installation

In addition to the previous, "per-machine" installation mode, a new installation mode is offered. It allows the user to install the application only for himself. In this mode, setup does not modify any per-machine settings. In addition, a user does not have to have administrative rights to install the Hex Editor Neo. After the product is installed in per-user mode, it is not visible to other users of the computer, but may also be installed by them in per-user mode.

Limitations

Take the following limitations into account when installing Hex Editor Neo in per-user mode:

This mode is not supported on Windows 2000.
On Windows Vista and later operating systems, standard user (and even computer administrator without elevation) does not have enough privileges to create System Restore points. This does not apply to administrator user on Windows XP computer. Setup always tries to create a system restore point, but will silently ignore this step if it does not have enough privileges.

Portable Installation

Another new installation mode is used to make a portable copy of Hex Editor Neo. Once installed, the copy of the product may be transferred to other locations, or to other computers where it can be used without installation. In this mode setup allows the user to install the product on the removable media and network shares.

Limitations

Take the following limitations into account when installing Hex Editor Neo in portable mode:

Portable installation will not work on Windows 2000.
Setup does not create shortcuts, does not update system registry and does not publish installed application (it will not appear in Add/Remove Programs Control Panel applet (Programs and Features starting with Windows Vista).
You will need to manually delete product installation folder in order to remove the product from your computer.
Setup does not register Hex Editor Neo's type libraries, preventing you from using the product in scripting environment.
Setup does not register Windows shell extension, making "Edit with Hex Editor Neo" and "Edit with Hex Editor Neo (shared)" context menu options unavailable.

Command-line Parameters

New Hex Editor Neo's setup allows you to specify several parameters on the command line:

Parameter	Description
-silent	Surpress any user interface dialogs during setup
-uninstall or -u	Turn on uninstall mode
-portable	Turn on portable mode
-prop INSTALLDIR=[path]	Specify the installation folder location. Must end with a backslash.
-user	Turn on per-user mode
-machine	Turn on per-machine mode

Examples:

This will install Hex Editor Neo in per-user mode into the "c:\Programs\Hex Editor Neo" folder:

          hex-editor-neo.exe -user -prop "INSTALLDIR=c:\Programs\Hex Editor Neo\" -silent

This will uninstall the Hex Editor Neo:

          hex-editor-neo.exe -u -silent

Version 4.85

Below is a list of changes in Hex Editor Neo 4.85:

Shared Files Support

Hex Editor Neo is now capable of working with files shared with other applications. Using the File » Open » Open Shared File… command you can open a file in the editor, at the same time allowing other applications to make changes to the file.

This feature is supported on all operating systems Hex Editor Neo natively supports. A shared file may be located on a local, removeable or remote media formatted with any supported file system (FAT, FAT32, NTFS, ExtFS…)

After you open a shared file, Hex Editor Neo starts watching for file's modifications. If another application makes changes to a file, Hex Editor Neo displays a Shared File Conflict Dialog, which gives you options to ignore a change, update editor's copy, and/or merge changes with local changes.

In addition, for all "update"-kind options you may instruct the editor to compare the new version with a previous one. Two file comparison algorithms provided by File Compare module are supported. Hex Editor Neo also allows you to retain older versions of a file in the editor. You may edit these old versions as any other kind of document in the editor, save your changes and so on.

Hex Editor Neo also detects file deletion. In this case it gives you an option to close a file or continue working with it, retaining all the changes you made to a file.

A configurable option exists which governs how Hex Editor Neo reacts on file renames. If enabled, renaming a file in another application (like Windows Explorer, for example) automatically changes the file's name in Hex Editor Neo's interface (without any prompts).

Single selection mode option

"Single selection mode" option, which was previously only available in General Settings page (under name "Auto drop selection"), is now also available from the Select menu and on Selection Tool Window's toolbar.

In addition, a number of reported bugs have been fixed in this release.

Version 4.83

This version fixes a potential crash on application exit and introduces new formatted text output format: Assembler array.

In addition, MBR format (for Structure Viewer) definition is fixed (see mbr.h).

Version 4.82

Below is a list of changes in Hex Editor Neo 4.82:

Restore original file attributes: File Attributes tool window now offers a way to restore original file attributes, even after you modify them and apply your changes.
Auto completion in Explorer: Address bar in Explorer tool window now offers autocompletion.
NTFS streams support in File Compare: When compared files are identical, they are also checked for one or more alternate streams. A user is warned if two identical files contain NTFS streams.
2D graph in Statistics.: Statistics Tool Window now provides you with two graphical data representations, instead of one.
Extended goto in Disassembler: Goto command in Disassembler Window now allows you to go to a named function or method. Autocompletion is supported.

In addition, the following reported or known bugs were fixed:

Elevation bugs: When Hex Editor Neo elevates itself (on Windows Vista or later operating systems), elevate.exe process is not terminated and remains running forever. Fixed.
Invalid progress bar: Invalid progress bar is displayed for some operations. Fixed.
Crash in operations: Bitwise, arithmetic, shift and case change operations may crash when used in some configurations. Fixed.

Version 4.81

Below is a list of changes in Hex Editor Neo 4.81:

Full history tree window: You can now view the entire document change history in a special window. History is represented as a tree with a node for each document change. You can quickly switch between states, get more information about each state or execute one of the purge commands. Comfortable zooming and panning features are provided by the window.
Complete rewrite of command routing and toolbar customization system: This release brings completely new version of the command routing and toolbar customization subsystem. We have greatly optimized Hex Editor Neo's startup and runtime performance and brought greater flexibility to user interface customization. Built-in and user-created layouts now not only affect tool windows, but also change commands on default toolbars and size of their buttons.
Checksums and Statistics now store per-document information: Checksums module and Statistics module now store per-document information. For example, you calculate statistics for a document, switch to another one and calculate statistics for it as well. Now, if you switch back to the first document, Statistics tool window will immediately display information it previously calculated for the first document.
Changes in the Free Edition End User License Agreement: Free version's EULA now grants commercial usage of the free edition of the Hex Editor Neo.
Improved Explorer integration: "Edit with Hex Editor Neo" shortcut menu option is now added to drives as well.
Improved Windows dialog: Windows dialog (it displays a list of all opened editor windows) now automatically activates a window under the cursor. There is no need to click the Activate button anymore.

In addition, the following reported or known bugs were fixed:

Several bugs in Structure Viewer: A number of not critical bugs were found and fixed in Structure Viewer.; 32-bit integer types (both signed and unsigned) were incorrectly handled in big-endian mode. Note that this did not affect 32-bit signed and unsigned long types. This bug is fixed as well.
Decrypt function is not working: On some computers it was unable to run a Edit » Decrypt… command. This has been fixed.; A lot of small glitches that were in our "suggestion queue" have finally found their time to be fixed in this release.

Version 4.76

This release focuses on major performance improvement in one of the core Hex Editor Neo components, responsible for working with large files. (Hex Editor Neo considers files bigger than 64 MB on 32-bit systems and bigger than 128 MB on 64-bit systems as large files).

Careful optimizations and wiser use of system resources allowed us to greatly optimize this core component. As performance of most editor functions depends on it, we have managed to improve the speed of various functions from 2x to 8x!

The most boost is displayed in "cheap" operations, like General Statistics and Pattern Statistics, moderate boost in heavier functions as Replace All and less boost in "heavy" functions like Find All, for example.

In addition, document saving performance has also been greatly improved. On some of our test platforms, file copying (File » Open command followed by File » Save As… command) works faster than in Windows Explorer!

In addition, several reported bugs have been fixed.

Version 4.75

New and updated features in this release:

Revised Operation History: User interface for document operation history has been completely revised. Now it is much more comfortable to use one of the most powerful and unique Hex Editor Neo's features - history branches.
Application load-time improvement: A lot of attention in this release has been paid to reduce the time Hex Editor Neo needs to launch.
Offset display type: An offset (or address) may now be displayed as hexadecimal, decimal or octal numbers.
New view types: In addition to hexadecimal, decimal, float and double, data in editor windows may now be displayed as octal and binary values. All Hex Editor Neo's commands and modules are also compatible with new view types, including Copy & Export module.
New range rule type in Pattern Coloring: Pattern Coloring introduces a special rule type: range rule. For range rule, you define a range which is then hilighted in a document.
Advanced support for Editor Window settings: You can now configure the default editor window settings on special settings page (Tools » Settings » Editor). These settings include offset display type, data display type and grouping, byte ordering, a number of columns, character encoding and visibility of code pane and text pane. In addition, there is a special option to associate a different set of window settings for each opened document and restore them next time the document is opened.

In addition, several known and reported bugs have been fixed.

Version 4.73

New and updated features in this release:

Windows 7 Beta support

This release introduces support for new cool features of the Windows 7 Beta taskbar. Progress indication and jump lists are fully supported and utilized by the Hex Editor Neo, and in addition, user is in control of customizing the tasks presented on the taskbar.

Structure Viewer

New structure formats: RAR, ICC, VHD, ZIP, TIFF, WAV, TGA, PSD, PIC, PCX, PAL, EMF, EPS, CAB, MBR, CDA.
New column: Size (to see the size of the field).
See also below for a list of fixed bugs.

File Compare

Recompare Files command added.

Color picker dialogs

A color may now be selected with a double-click.

Bugs fixed in this release:

Structure Viewer

The following bugs are fixed:

Nested pointers are not supported.
Array size is parsed incorrectly if multiplication is used in size expression.
Invalid script file causes a crash.
Several parser bugs fixed.

Find in Files

Deadlocks and possible crashes were fixed. In addition, performance for the feature has been increased.

Explorer

Several bugs are fixed in Explorer and it is now compatible with Windows 7 Beta.

Version 4.72

New and updated features in this release:

Disassembler: Version 4.72 brings support for x64 executable files.

In addition, a bug that sometimes lead to program crash has been fixed.

Version 4.71

New and updated features in this release:

Disassembler

Version 4.71 brings support for .NET assemblies. It also features an updated disassembler view window, with support for fast navigation, selection of assembly text, column configuration and much more. It also allows you to display an assembly listing in AT&T format.

Disassembler has an improved quality of the assembly listing. Module imports are now also analyzed and displayed, in addition to symbols.

Structure Viewer

The most of the new functionality is within the Structure Viewer module again. It now understands new built-in types, statements and directives. It also supports variables, constant and variable arrays and expression evaluation with dynamic type inferring.

This release eliminates most of previously imposed limits on structure size, array size etc. The Structure Viewer Tool Window has been updated to easily handle billions of items with very fast and clean navigation. Commands like Expand All and Collapse All will take less than a second expanding/collapsing a structure with a billion of items. If you bind a complex structure to a huge file (for example, AVI), you can estimate the editor to easily carry the job without running out of memory.

A number of handy features, such as Synchronize Position (which works "both sides" - from structure to document and from document to structure), Mouse over field tracking (which highlights a field under the mouse cursor) greatly simplify the file structure analysis.

Structure definitions may extend their functionality by referring to functions written in JavaScript or VBScript. These functions have access to the underlying parser and document, thanks to the IFileDocument and IParser interfaces, exposed to them by the Hex Editor Neo.

The overall compilation and binding performance has been greatly improved.

There is a special topic in this documentation that describes the changes in the Structure Viewer module.

Copy&Export

The Advanced Copy & Export module now follows the model offered by the editor window. It now allows you to execute the Copy and Export commands with no selection present. In this case, a cell under the cursor is copied/exported.

The current byte order is now taken into account when performing copy or export functions.

It also offers an option to configure the number of digits to be exported for floating-point and double precision floating-point types.

Refresh View Command

When working with logical or physical disks, process or physical memory, this command allows you to refresh the editor window to display any possible changes to the underlying data, performed by some other application or operating system.

/s Command-Line Parameter

When launched with "/s" command-line parameter, Hex Editor Neo forwards the list of files to open to an already running instance, if there is one.

"Display cursor address on the left" Option

Several customers complained about the address of the cursor location being displayed at the start of the line. Now this functionality can be switched off. See the General Settings topic for more information.

Reverse Sorting on Statistics Columns

Statistics window now allows you to sort columns in both ascending and descending order in its table mode.

New IFileDocument Methods to Be Called from Scripts

A previously introduced ISequence object was called to make it possible to call methods of the IFileDocument interface from scripting languages (such as JavaScript and VBScript). Although, our tests has shown, that in some cases it is still impossible for a script to call one or another method due to the limitations in the Automation model and the way scripting engines are implemented.

This release finally resolves the problem by providing a special variant of each affected method. Every such variant may be easily called from the scripting languages.

Go to in Process

Go to in Process command now interactively updates the cursor position when you click on the image sections or modules (without closing the Go to window).

UI Sugar

You can now make any tool window appear as a tabbed document. That means that the tool window will not be dockable to one of the four sides of the main window anymore, nor it will float over the main window, but instead will be placed where all editor windows reside. You may then take advantage of the Editor Window Placement feature to position a tool window.

Each tool window now also memorizes its floating position separately of its parent frame.

Ctrl+Mouse Wheel now quickly changes the font size in an editor window. This is a quick way to change a font size without using the Layouts dialog.

The following is a fixed bug list:

Purge All History and Load History Commands: These commands did not work properly in Free Edition mode.
Copy&Paste Bugs: Several bugs with copying and pasting document data have been found and fixed. This may include several application crashes.
A Lot of Minor Bugs: Quite a few of minor bugs or inconsistencies were found and fixed throughout the product.

Version 4.64

New and updated features in this release:

Structure Viewer

Structure Viewer has been completely redesigned and rewritten. It now supports a sophisticated structure definition language with expression evaluation, pointers and bit fields, case unions and assertions, constants and enumerations and much much more.

In addition, C99-compliant preprocessor is run before a source file is compiled, a preprocessor with full support for macros and conditional compilation.

Source files are optimized and saved into precompiled files, which are then quickly loaded by Hex Editor Neo on demand. Structure binding performance has also been greatly increased.

In addition to the ability to bind a structure to an absolute or relative address or to a cursor position, a structure may now be bound to an expression. This expression may reference constants and enumerations declared on the global source file scope or even reference previously bound structures.

Scripting

New Sequence Object provides scripting languages (such as Javascript and VBScript) a way to build a pattern and pass it to File Document Object methods that require a pattern.

Version 4.51

A number of reported bugs are fixed in this release. Hex Editor Neo version 4.51 introduces a major performance boost.

Thanks to a new internal data structure and handling algorithms, a major performance boost is found in the following functions:

Fill, Delete, Cut and Paste - when they operate over a multiple selection - have up to 3x performance boost.
Find All, File Compare, Selection Loading - up to 10% performance boost.
Replace All - from 1.5x to 2x performance boost.

Similar numbers refer to Find in Files and Replace in Files functions.

New features in this release:

Disassembler: Hex Editor Neo now includes a disassembler module. The current implementation is capable of disassembling 32-bit x86 code, including support for FPO, MMX, SSE, SSE2 and 3DNow! instruction sets. Disassembler automatically searches for symbol files and uses the information from them to increase the assembly output readability. The Disassembler View may be connected to ordinary editor window which provides you with another handy data viewing and manipulation tool. The disassembler module works with files and processes' memory and is even automatically updated when you modify the document.
Regular Expressions: Find, Find All, Replace, Replace All, Find in Files, Replace in Files, Pattern Coloring and Pattern Statistics commands and modules now fully support regular expressions. ECMAScript-compatible implementation of regular expressions provides you with extreme power ever found in binary editors. Very efficient implementation of "bulk" commands (Find All, Replace All, Find in Files and Replace in Files) combined with unique features of Hex Editor Neo's multiple selection feature, together form an invaluable editing tool. A concept of named regular expression classes even allows you to define recursive grammars.
Window Switching: Hex Editor Neo now provides fast and convenient tool that can be used to instantly activate any visible tool window or editor window. When you press Ctrl + Tab or Ctrl + Shift + Tab (user configurable), a navigation window is displayed. It provides the list of visible tool windows and all opened editor windows for you to activate. See the Window Switching section for more information.
Code Pane: Hex Editor Neo now provides you with a method to completely hide a code pane, leaving only the text pane visible. Combined with the auto columns mode, it is a powerful tool to edit text or binary-text data.
Default Layouts (Three Different Ones): When you run the Hex Editor Neo for the first time, you are provided with a choice of default working layout. You can choose between a "Novice User Layout", "Advanced User Layout" and "Expert User Layout". You can later change the chosen layout or make your own. See the Default Layout section for more information.

Version 4.41

Version 4.41 fixes a number of reported bugs and introduces some performance optimizations. New features in this release:

Case Change Operations: Hex Editor Neo now offers three new Data Operations: Lower Case, Upper Case and Invert Case. Case change operations take into account current encoding and are capable to work with Unicode data.
Application-Wide Byte Order Support: Hex Editor Neo now fully supports both little-endian and big-endian byte orders. Different byte order can be set separately for each editor window and there is an option that controls whether floating-point types are affected by byte order change. Byte order change commands have been removed from Data Inspector and Structure Viewer modules, as they now respect the byte order configured for a window.
Modify Bits Command: New Modify Bits command allows you to see a visual binary representation of the number and modify individual bits.
Printing Support: Full printing support is now available in Hex Editor Neo.
Copy and Cut Work Without Selection: Copy and Cut commands can now be used when there is no selection in the current editor window. In this case, only the cell under the cursor is copied/cut into the Clipboard.

Version 4.33

Hex Editor Neo version 4.33 fixes a number of reported bugs. Affected modules: Data Inspector, Structure Viewer, NTFS Streams, File Compare.

It also adds the "Hide All Tool Windows" command on the toolbar so you can quickly maximize the workspace and then return to the previous configuration at one mouse click.

Version 4.32

Hex Editor Neo version 4.32 fixes a number of reported bugs and introduces a lot of new cool features. New features in this release:

New Document Types

Hex Editor Neo is now capable of opening volumes, physical disks, process virtual memory and computer physical memory (on supported operating systems).

New Editor Commands

Encrypt and Decrypt commands may now be used to encrypt and decrypt a document (or part of it), using one of the installed block or stream ciphers.

A large set of new data operations: bitwise (NOT, OR, AND, XOR), arithmetic (Negation, Addition, Subtraction, Multiplication, Division and Remainder) and shift (Logical Left and Right, Arithmetic Left and Right and Rotation), are provided. They operate in linear time (depending on selection's complexity), that is, for single-range selection they execute immediately, regardless of data size.

File Comparison

Hex Editor Neo provides two methods, simple comparison algorithm and difference algorithm to locate changes between two files.

Little-endian/Big-endian in Structure Viewer

Structure Viewer may now be switched between little-endian and big-endian data representation.

Version 4.21

Hex Editor Neo version 4.21 fixes a number of reported bugs, provides a number of optimizations as well as introduces new cool features. New features in this release:

Performance Optimizations

This release has undergone several performance optimizations resulted in significant speed-ups in the following commands and features:

A special image cache speeds up application loading time. This special cache stores pre-rendered vector images (which are used throughout the Hex Editor Neo) to significantly reduce the application startup time, which was very small even before this cache was implemented!
A number of algorithm improvements allowed several editing functions to operate much faster and consume much less RAM. This include typing, inserting and deleting (with complex multiple selection).
Several improvements were made to the Find in Files feature, leading to much less memory consumption by this function.
File saving algorithms undergone several optimizations leading to smoother and faster saving.

NTFS Streams Support

Hex Editor Neo now fully supports NTFS alternate data streams. A special NTFS Streams Tool Window displays all streams for the currently active file, allows you to delete or rename them, open them for editing or create new streams.

In addition, the powerful Find Stream feature allows you to locate all streams on your computer.

File Attributes has also been updated to display more information related to streams: the total number of streams, size of all file's streams and the total size occupied by a file (including all its alternate streams).

Find in Files now has an option "Include streams" that you may use to include alternate data streams in Search or Search and Replace operations.

Version 4.11

Hex Editor Neo version 4.11 fixes a number of reported bugs as well as introduces new cool features. New features in this release:

Built-In Explorer: Hex Editor Neo now has two Windows Explorer-like windows as part of its user interface. They can be used to perform usual file and folder operations and also tightly coupled with Hex Editor Neo. For example, you can open files in the editor by double-clicking them in the Explorer window simply dragging them to the editor's window.
Encodings: Hex Editor Neo is now capable of displaying text in the text pane according to a selected encoding. More than 130 different encodings are supported (subject to installed code page files and fonts). When the cursor is in the text pane, typed characters are also converted using the selected encoding. Encoding can be set separately for each editor window. Different ANSI, UNICODE, ISO, OEM, MAC, EBCDIC and country-specific encodings are supported.
Checksum Calculation: Hex Editor Neo supports 16 checksum calculation algorithms, including MD5, SHA-1, CRC-16, CRC-32 and others. Custom CRC algorithm is also provided. You can compute the checksum for the whole file or for the current (multiple) selection. Several checksums may be computed at the same time. Results are easily exportable and copyable to the Clipboard.
Advanced Copy & Export: Selected document data may now be converted into a number of supported text formats and placed into the Clipboard or exported to a file. Space-separated or comma-separated numbers, raw text with selected encoding, programming language array declaration, Base64, UUencode and Quoted-Printable are among supported formats.
Pasting Text: Text may now be pasted into the editor. Depending on the active pane, the text is either pasted "as is" (if the text pane is active), or parsed as a sequence of hexadecimal or decimal integers (if the code pane is active).

Version 4.01

Version 4.01 is an absolutely new release, designed and developed from scratch. It does not contain any code from the previous product version.

On the other hand, Hex Editor Neo shares some code base with our Serial Monitor and USB Monitor products, which are part of the Device Monitoring Studio product.

Hex Editor Neo retains all interesting and useful features of its predecessor, such as multiple selection, multiple editor windows, vector icons and bookmarks, but implements all these features in a new way, significantly lowering memory requirements and increasing performance and stability.

The performance of all functions has been significantly increased. Several functions that previously executed in several steps now execute in one step (this includes Replace All command, for example).

Hex Editor Neo does not longer support Windows 98 and Windows ME operating systems. But the list of supported operating systems has actually increased:

Windows Vista (x86)
Windows Vista (x64)
Windows XP (x86)
Windows XP (x64)
Windows Server 2003 (x86)
Windows Server 2003 (x64)
Windows 2000

Pentium III or newer processor is now required by the Hex Editor Neo.

A lot of new features have been implemented in this release. The full list is provided in the Hex Editor Neo's Features section.
