DSynchronize is a freeware real-time bi-directional file synchronization utility for Windows XP and Vista. It allows you to synchronize; in real-time; files and folders with multiple devices including Hard Disk drives, Floppy Disk, LAN, external USB flash drives, CD-DVD (with packet writing software) and FTP server.

The program compares every directory “Source” with the respective “Destination”, then changes the “Destination” (adding, replacing, or deleting files and subdirectory) in such way to make those files or subdirectories identical to the “Source.”

The software is very flexible in terms of configuration:

1) You can specify filters for every folder in the source and destination such as by file extension, files modified date, subfolder inclusion/exclusion, etc
2) Schedule or synchronize in real-time
3) Copy only newer files: Replaces files in “Destination” only if the file in “Origin” is more recent
4) Bi-directional or uni-directional sync
5) Autostart program as service on Windows startup
6) Confirm before adding, deleting and replacing files and select the one you want to exclude while moving
7) “Antifragmentation” reduces the fragmentation of the disk: In order to prevent holes in the file structure when a file is replaced, the old file is first removed from the structure and then the replacement file is written into the old file’s place.
