This free sync program is the best! No need for commercial products anymore after discovering this. Been using it for a few months now. Never gonna look back! With each new release speed and features have increased.

Saved my life. Now it takes me 30 sec instead of 45 min to update my 8000 files / 4 GB on LAN. I learned it in 30 sec. Simple and reliable.

Does pretty much everything I need to do better than MS Synctoy. I had started off with Synctoy hearing good things until I found out it won't copy files that are in use. Now I'm using FreeFileSync to sync my XBMC database from my media center to my regular PC. It works like a charm. I also use it to keep my music synced across 2 computers (I like having it in both places) as well as my Portable Apps. It reads the changes ridiculously quick, copies files in use, and the interface stays relatively responsive.
