Most useful application. During all these years that I've been using it, it has gotten better and better.

I've been using FreeFileSync for two years and it is great. I donated through PayPal :-)

I got a similar app from PC Magazine a few years ago. I never really figured out how to use it. I tried to start it up and it would not load for reasons unknown. I googled just in case I might stumble across... THIS! It did precisely what I wanted to do. I figured out how to operate it pretty darned quick, which is a testament as I'm gettin' old and am not as fast on the uptake as I once was.

I wanted to synchronise a Windows 7 64-bit Notebook, an iMac (Lion) with Samba enabled. I have a lot of data to synchronise, about 150 GB and 200,000 files. I've tried SyncToy from Microsoft, Windows 7 built-in synchronisation center, AlwaySync, Syncback, SkyDrive, and so on... Each of those tools took VERY long in the good case, or hanged in the bad case :-(
And I tried FreeFileSync: It does exactly that I wanted to do, and it is really very fast. It scans my 200,000 files in only 2.5 minutes!!! So I'm VERY happy with FreeFileSync.
