File Sync is a robust file sync solution that automates the synchronization of data between Windows NT4/2000/XP/2003 servers without agents or scripts, File Sync not only synchronizes files and folders, but also migrates NTFS permissions, file shares, file share permissions, local users and groups, and compression settings.
File Sync can be very useful if you have two harddrives and want to synchronizes your data regularly. Neither you need an expencive RAID-Controller which mirrors the whole harddisk (and also all directories, you can't specify it) nor you need to copy the directories by hand (and maybe forget it). With the File Sync Tool you can keep your data backed up and safe.
