Thumbs up Stratos reviewed FreeFileSync:

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.

Thumbs up the-nightowl reviewed FreeFileSync:

Maybe the best synchronisation program you can get: it's fast and intuitive, relatively easy to learn, and, most important, very reliable.

Thumbs up Paari reviewed FreeFileSync:

I tried many backup software before FreeFileSync. Let me tell you, this is the most user friendly backup software I have seen. I have been using this for the past 2 years and found it very useful.

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.
