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.

After the death of my home's NAS I was in big trouble... But now, thanks to FreeFileSync, I have all my data saved in a so easy way that I am not looking for another NAS. A couple of external cheap hard disks are enough!! (and FreeFileSync, of course) :-) I am sharing my experience through my international contacts. Hoping to find more supporters for your GREAT work. Thanks for all.

I use FreeFileSync for months and I am very happy with this software. Thank you and congratulations to those who developed it, improve it and update it regularly.

Since I am a backup paranoiac because I have lost data several times, I want something that is quick and painless. This is super easy to use. It also, since it does not give me an error message, copies all the files that a windows copy and paste would not copy because the file names are too long or they are organized in too many sub-folders (what a hassle that is, but that is another windows problem). Have I confirmed this by testing and verify copying? No. It is easy enough to do, but I am way too busy.
Just like people believe in their country and a God, I believe in FreeFileSync. The best part is that you are not spammed with advert pop ups or anything like with other freeware. Thank you so much FreeFileSync!
