I'm using this tool for quite some years now. It's better than all the others I've tried before, and in addition it's completely free! Thanks a lot for your splendid work!

I am a 20yr IT vet (really!) I do minor programming and I have had the need for a feature rich program that will get the files from A to B without issue and save security information. FFS is simply the best in the market hands down. The fact that it is free totally blows me away!

Since my initial review we have come to use this product in our daily processing. The fact that the developer truly listens and incorporates good effective additions as well as continuing to improve the product puts him ahead of even larger software houses. Please keep up the good work and look for our donation! James Lee Outsource Technologies Inc.

Happy User
A GREAT piece of software that rivals other expensive software. Very versatile and always expanding. The developer is very helpful and responsive. Couldn't live without FreeFileSync!
