User Reviews

"I've been using this for a couple years now to back up to my USB drive and it works flawlessly. Keep up the good work! :)"

Luke Matthews

"Thanks for a great app. It really gives peace of mind knowing that files are backed up right. Especially when I discovered image programs aren't transferable to another computer. FreeFileSync files are. Yeah!"

Dale Dudas

"It's a very good program! Very useful! Thank you for creating this program. From South Korea"

Kim Han

"Best out of all 5 sync programs I've tried, both commercial (Goodsync, AllwaySync) and non-commercial (SyncBack, SyncToy). Don't waste your time trying other "commercial" ones. THIS IS THE BEST."
