Example: A 'blank' patch is 150 kb unstuffed. Compressed with StuffIt 7.0 (or newer), you obtain a 40 kb file.

If your application is about 1.5 Mb with a 1 Mb executable file, and your new version has only a few changes, your patch will be about 210 kb unstuffed. Compressed with StuffIt 7.0, you obtain a 56 kb file ! If your application is 2.5 Mb with a 500 kb executable file, and your new version has only a few changes, your patch will be about 200 kb unstuffed. Compressed with StuffIt 7.0, you obtain a 45 ko file ! Of course iPatch can replace, create or delete pictures, .icns or .nibs that are contained within your application.
