AgenSoft announces the Final Release of PatchFactory v3.1 for Windows 98/Me/NT/2000/XP/2003, patch and update building tool that is used for creating compact software, documents or just single files updates from old version(s) to the new one.

Key features of PatchFactory v3 :

Patch building:
- Comparing files with size up to 2^63 Bytes (~8589934592 Gb).
- Significantly increased the comparing speed.
- Significantly increased quality of file-comparing.
- Utilizing of the registry, INI files or a fixed path for smart file location.
- Cumulative patch building to integrate several updates into one patch package.
- Storage of difference building results in intermediate files helping significantly increase the speed of reiterated patch building.
- Flexible control under ratio "time/result" with the help of different comparing methods selection.
