Thumbs up ray reviewed FreeFileSync:

This has to be the most useful free tool ever released. I'm a network administrator and when moving file servers, this tool outperformed Robocopy, Symantec, and many many others.

Thumbs up Sam Gerber reviewed FreeFileSync:

I've used Microsoft's SyncToy for years and thought it was the best of what was available ... that is, until I started using FreeFileSync. There's no comparison in terms of all the things that are important: ease of use, performance, flexibility.

Thumbs up magickz reviewed FreeFileSync:

Very cool. Now it helps me to keep folders in sync and backup files from internal and external hard discs, mp3 player and my phone... :-) Many thanks to the developers.

Thumbs up drujo reviewed FreeFileSync:

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!
