Thank you for continually filling a huge gap and for making things possible that were previously only dreams!
Tiziano Riolfo
Really appreciate this great piece of software. Easy to use, but with a powerful interface. Keep up the great work!

Just started using FFS: Majestic software for backup. I promise to donate after a few months of use. I was using Microsoft SyncToy which MS never tried to improve. Kudos FFS Team.

I've tried almost every files and folders synchronisation program available on windows. And FreeFileSync is definitely the best. It's the fastest, the most customisable and the most intuitive one, and above all, it's open source.
