Thumbs up: This is the best file synchronization program that I've found. It is fast, stable, and has the right features without being bloated. The author has done a lot of careful thinking about how the program should work from the user's perspective, and (more importantly) how it works under the covers.

Thumbs up: I've tried several sync tools, and this one is the best, I've being using it for almost 2 years and it works fine, What I don't like is that the latest version 5.3 (don't know if 5.2) has adware inside, it contacts opencandy website and prior to installing the program another program is suggested for you to install, Just be careful in that screen to NOT select that other app. I understand that sometimes open source developers use that to have some income. Overall it's the best sync tool out there, and it's freeware and open source !
