Thumbs up George ALEFantes reviewed FreeFileSync:

I have worked with Vice Versa and FreeFileSync. There is no comparison. FreeFileSync is one of finest and most important applications ever written. It works perfectly and handles a critically important computer task that too few people do. Vice Versa had at least one fatal flaw that was insurmountable: If folders had to be created on the destination side, they were created in all lower-case, regardless of the case of the source side. Consequently, the subsequent compare always failed. Their tech support was supposedly unaware of the problem, could not resolve it, and eventually avoided further contact. FreeFileSync is as good as it gets.

I've been looking for a tool like this for about 3 years, when my most favorite directory sync tool stopped development, short of Windows XP. GREAT work on this. Clean, efficient, simple dir comparison or sync. Run it and it shows you what's out of sync, without all of the complicated configurations, etc. that other dir sync tools have. Thanks.

Just perfect for syncing local and/or network drives. Best free tool I have ever found. I run it on Debian (how about packaging it in .deb?) and in windows portable versions. Congrats to the team and thank you.

I created an account just to post my praise to the author. Class A material. DFS Replication with Windows Server was proving to be a nightmare. Deleting files without reason, failing to replicate in both directions, erroring out, just becoming an overall headache.

This solution was not only intuitive to use, easy to integrate, and easy to confirm functionality (The log files are heaven sent - They are concise and to the point yet in depth and serve a purpose), but is extremely powerful with the configurable batch jobs. Kudos to the author, and thank you for providing such an awesome product. :)
