FreeFileSync: Folder Comparison and Synchronization

In this video tutorial you'll get a quick overview on what FreeFileSync can do.

FreeFileSync is a free Open Source software that helps you synchronize files and synchronize folders for Windows, Linux and macOS. It is designed to save your time setting up and running data backups while having nice visual feedback along the way.

Been using this for 3 years now. Keep up the good work!

Amazing, this is the best file sync ever!!!

[GeorgeNoiseless]

Folks, if you use this great tool share it with others! Right now it's far too obscure for how incredibly useful it is.

I think this is the best so far those I tried. However after synchronization, good to show all the files again to give "new" users a sense of confidence as they often wonder where did all my files went.

Çok kullanışlı, muhteşem ve sürekli kullandığım bir program. Emeğiniz için, emeğe geçen bütün yazılımcılara çok teşekkür ederim. 👏👏👏👍💖

do you guys have an android app version ? i mean i got a music folder on my PC that i sometimes copy over to my phone and since i can't tell which of the 500 songs i added, removed or edited, i end up deleting all of it and copying it again.
I could also use it to only download new photos i've taken.

Do you need FreeFileSync to be installed on multiple systems if you want to sync from a network drive?

[Gorky]

On my external backup HDD, I delete a folder then I copy-paste the same folder from system HDD to get the latest updated data. How I see this app. compare those folders and remove file(s) or make a copy on backup HDD, right?
Can it work with C:\Users folders?

[spazzychalk]

Does this remove folders that no longer exist? My old sync would only delete the files and leave the folders

[Benl]

Does it work with compressed .zip files?

[ERMAC]

So I use this but have some questions, is this a good spot, I'm looking for the official support page ? If I have file that are not completed 100% . There in the process of downloading and I use the update option, how does that work ? So let's say I have downloaded 25% of file A and then use the update option. I can still do this and the next time I update if file A is now at 100%, it will just update that file as 100%? How does it know by just comparing the names?

[FreestylerAlbert]

Is it possible to limit the memory usage of the app? I'm a bit disappointed it uses 40gb+ RAM when I compare a lot of files. Or there is memory leak in it too.

I did not find a scheduling option that would do the backup at a certain time
