Customizable Editor Color Schemes

You can customize the every visible aspect of the editor window, that is, the font and colors of each window element may be customized. For convenience, these customizations may be saved as a scheme.

Patch Creation

A patch is a difference between two states of a document. In most cases the size of this difference is much smaller than the size of the file itself. Hex Editor Neo supports creating a special patch file, which contains all modifications made to an opened document. The patch can subsequently be distributed and applied to the same file resulting in the same modifications being made to a file.

Hex Editor Neo does not support applying patches in its framework. Instead, the separate application, PatchApply.exe is provided for this purpose. Alternatively, Patch API provides several other methods of applying patches.

See the Creating Patches section for more information.
