DataSync

This is useful if you want to make regular simple backups of files to a network or removable storage device, or if you just want to compare the contents of one folder to another.

DataSync is freeware and works on Windows 9x/NT/2000/XP/Vista/Windows7.The upgrade package only contains the files required to upgrade an existing installation to a new version. This file will not work on it's own, so don't download it unless you have previously installed a full installation package.
