OmniPatch is a program for creating and applying patch files, the format designed to identify and log the differences between any two files. Once created, the patch file can be used in conjunction with the first (original) file to create the second (modified) file.

The fewer differences between the two files, the smaller the resulting patch file will be. OmniPatch files have the extension 'omp'.

Great - it doesn't seem to handle resource forks or folders, yet it doesn't use the standard diff format as far as I can tell. So we get an incompatible format that offers no advantages other than a whizzy GUI. Which could have been put on top of diff/patch.

It's free. If you don't like it, don't use it.

The OmniPatch format is already an established format in a few niche community (for example, Myth).

This is just an overhaul of the GUI for OmniPatch which is much easier to use than previous apps.

The application's help notes the following:

OmniPatch Limitations

Currently, OmniPatch cannot create a patch between two folders or application bundles.

Also, file resource forks are entirely ignored by OmniPatch.

These issues may be addressed by a future version of OmniPatch.
