- Suppose that you must send to smb. a 5mb file via e-mail (or other way) each
- two or three days. Suppose that only 8% of this file is changed and 92% of
- its contents remains the same. First time you send whole 5MB file. But after
- that you don't need to send all 5MB. You should use program which will "find"
- these 8%,"cut" them from the file and send only this small portion. And later
- on receiving side combine received 8% with old version of the file.

- Difference Maker compresses file taking into account previous file version.
- Data integrity is checked with CRC32 algorithm. Diff Maker was designed for
- working with huge files (50-100MB isn't a problem) and optimized for speed.
-
- For example we use Diff Maker for compressing database dumps. Also Diff Maker
- can be used for creating installation packages when newer version of program
- wasn't changed too much from older version.
-
-
- Run diff.exe without parameters and help will be shown.
-
- Now compressed with diffmaker files can be compressed with ordinary
- compression program (RAR,PKZIP,etc.) /it will reduce size of the delta file/
