I have used a lot of sync tools. I am sure FreeFileSync is one of the best tools available in the market out there. Above all it is free!! Thanks a lot to the dev team for contributing such a wonderful product.

cadbloke reviewed FreeFileSync:

Awesome. Much more versatile than SyncToy. I love the fine-grained control and also the option to preserve deletions. I use it on a couple of identical external HDDs for off-site backups. Different drive letters? No problem, just copy the XML config file and change the drive letter. Save. Run. Done.

Really replaces rsync for windows.

Theo reviewed FreeFileSync:

Awesome scalable tool!!!!! This is the only tool I know which can compare and sync 2 directories with more than 11,000,000 files, and not die while syncing. It took my server a couple of days to sync those monster directories, but hey ... I'm happy! - Theo Ekelmans Ordina Datacentre services.
