An excellent program with several unique features of its own. Can handle some stuff that even some fully commercial products can't.
Zenju is very responsive to queries, active in the help forums and always striving to make it better. What more can we ask? I like it so much I've hit up Paypal and sent him some cash. Well worth it.

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.

This is ***THE BEST*** It managed all of my 80,000 files in 489 directories: No problem!! I have tried at least 10 different sync tools in the past 10 years. This is wonderful. It is a 'good looking' friend of rsync!

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.
