What a simple yet incredibly helpful and powerful program! The user interface is flexible enough to house lots of things or to be very simple and sleek - and it performs binary comparisons! Cheers for a job well done!

After the death of my home's NAS I was in big trouble... But now, thanks to FreeFileSync, I have all my data saved in a so easy way that I am not looking for another NAS. A couple of external cheap hard disks are enough!! (and FreeFileSync, of course) :-) I am sharing my experience through my international contacts. Hoping to find more supporters for your GREAT work. Thanks for all.

Thumbs up Andy reviewed FreeFileSync:

Definitively the best sync program available. I've tried multiple others, even commercial ones. No comparison to this one!

Now that the venerable FileSync has mysteriously stopped working on my PC, I am relieved to find FreeFileSync works well for me in similar ways.
