Updater - an effective tool to create patch packages for software and file updating.

Instead of uploading different versions of similar files to the server (e.g. a new version of the program or data file), you can upload just the differences between the old and new file (update). The update file is usually much smaller than the entire file of a new version, that will effectively decrease the traffic from your server.

Features:
* fast performance means processing large files in a short time;
* process entire directories and directory trees;
* highly compact update files using a strong compression algorithm;
* easy-to-use and clear interface.
* cross-platform operability - can create updates for all Windows, Linux, FreeBSD, and other UNIX platforms (on demand).

Free for non-commercial use.
