Document represents a file, shared files, disk, volume, process memory or physical memory, opened in the Hex Editor Neo for viewing and editing. Each opened document has at least one editor window associated with it. You can also have multiple editor windows for an opened document.
Hex Editor Neo does not allow you to have multiple documents for a single file, but you can open as many windows for each document as you need.
Any file opened in the Hex Editor Neo is accessed with Read Only access. Sharing access is set to allow Read operation only. This means that you will not be able to open a file that is already being used by any other process if that process does not grant Read sharing access.
When you open a disk, volume or a process memory, they are also always opened with Read Only access, but no sharing restrictions are applied. That is, if some other application changes the contents of the edited documents, you will need to scroll document's editor window to view changes.
If there are any errors the editor encounters during opening files it displays the list of failed files with corresponding error messages. The following window is displayed regardless of the way you chose to open files, in case editor encounters any errors trying to open them.
