I've been using this tool for a while now and it's simply awesome. Former SyncToy user. Best way to keep a Dropbox style of sync with my external drives. I also dig the new look. Very stylish.

This program is excellent. I have been using it between 2 computers for 3 weeks and no issues. I was using SyncToy for a few years with few problems, but recently SyncToy began to delete the newer files, some of which I spent hours writing. Thankfully I found FreeFileSync and it is working perfectly.

Excellent, works perfectly between my MAC and my corporate server based on a Microsoft environment. The only "bad" point that I see, is the usage of Realtimesync, a tool to automatize the synchronization when a folder becomes available. It's not fully explained how to manage more than one directory!

Excellent product! Backing up my digital photo collection is trivial, even as I move folders around, change photo ratings, etc.
