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.

space0ctopus reviewed FreeFileSync:

SO awesome. There's so much I could say about this indispensable program, but I'll just tell you now that the amount of options and different types of sync methods will ensure you are able to do what you need, as well as the ability to save your sync configurations for certain sync jobs, so that you can easily do them in the future.

Great UI, please don't change it, because too many people are ruining their software these days with some new crap that renders their software useless, literally making it impossible to do anything. Keep up the GREAT work, developers, you really know what you're doing <3 You rock mah socks! ^_^

Surely the best sync application currently including paid ones. Simply the best and works flawlessly. Meets the requirements of people who have to work on multiple systems.

godlymusic reviewed FreeFileSync:

Excellent, efficient tool for manual backup and folder mirroring. No persistent services. Does what it promises and is updated frequently. Takes advantage of multicore now. A big thanks to the developers.
