Danurica reviewed FreeFileSync:

The best sync util I've found. I am using it since version 3. It is the easiest way to keep a complete synced mirror from my laptop to my desktop user's folder. Highly recommended!!! A++++

hawktroy reviewed FreeFileSync:

Awesome program to sync files! It has extended features and allows quite some customization. Batch mode allows custom automation from command line (without missing features), which is very helpful for me.

Ottokar reviewed FreeFileSync:

Best tool for folder synchronization. The different settings for the right and left side are very good. I was looking for a long time for this tool. Thank you for your great work.

An excellent program with several unique features of its own. Can handle some stuff that even some fully commercial products can't.
Zenju is very responsive to queries, active in the help forums and always striving to make it better. What more can we ask? I like it so much I've hit up Paypal and sent him some cash. Well worth it.
