This program is excellent. I have been using it between 2 computers for 3 weeks and no issues. I was using SyncToy for a few years with few problems, but recently SyncToy began to delete the newer files, some of which I spent hours writing. Thankfully I found FreeFileSync and it is working perfectly.

The file filter specification (inclusion and exclusion) brings incredible power to this free software. Thanks for showing us that free can be (much) better than paid software.

Thumbs up nw0001 reviewed FreeFileSync:

The most amazing and useful piece of software I have. Particularly the versioning feature, which allows me to perform my backups with file history in a more useful manner than general backup software. It works well and is well designed.

I've been using this utility for more than a year now and still recommend it!
