I have used a lot of sync tools. I am sure FreeFileSync is one of the best tools available in the market out there. Above all it is free!! Thanks a lot to the dev team for contributing such a wonderful product.

One of the best sync programs I've found for Windows and Ubuntu. This software has a streamlined interface that allows access to the most frequently used features quickly. But also allows many advanced tweaks like what to do with deleted files etc. The program is fully featured yet not bloated. I've used it for about 3 years and really haven't found anything else this well written. Keep up the good work! Love it!

This program already helped me a lot, and I am not even using it to its full potential. I like how 'close to the user' the interaction with the files is. At every point in time I know exactly what the program does. When it comes to the safety of my files, this is how I want it to be. Thank you very much!

After trying other shareware-licensed software for data file syncing, I found FreeFileSync is a great tool to use. A simple, yet powerful data sync tool for Windows. And I'm amazed it's free. Highly recommended if you are after a simple tool that syncs your data to any drive, computer, network drive or remote cloud storage.
