Another question, so I have a folder DERU_beta_win, I push it with an exe Deru_beta_0.54.exe. What if I replace the content of the folder with for example Deru_beta_0.55.exe. Will butler make a diff?
It will attempt to make a diff, but .exes often don't diff well
If your game is a single executable, chances are it contains data compressed bundled within there - and compressed data doesn't diff well.
If you can, store your data uncompressed next to your .exe for optimal diffs :)
