fbsdiff

Dynamically generate and apply patch files to folders using bsdiff and bspatch (http://www.daemonology.net/bsdiff/). Useful when compressing & decompressing files to apply a patch is not a realistic option.

Generating patches with fbsdiff.exe

To generate a patch, use the following command strcture:

fbsdiff oldFolder newFolder patchFile

The generated file will be a .zip that follows the following structure:

=> create/
  => file_to_be_created.txt
  => another_new_file.png
=> patch.index
=> file_to_be_patched.mp4.patch
=> another_existing_file.txt.patch

Applying patches with fbspatch.exe

To apply a patch, use the following command structure:

fbspatch inputFolder patchFile

The patch.index file generated with the patch files contains instructions to every changed file. The instruction might be update, create or delete. Currently, renamed files are not recognized (they will be deleted and then created again with the new name). This will be added in the next version by generating a hash for the file and checking its integrity.
