About FreeFileSync
FreeFileSync is a folder comparison and synchronization software that creates and manages backup copies of your important files. Instead of copying every file every time, FreeFileSync determines the differences between a source and a target folder and transfers only the minimum amount of data needed.
NOTE:
FreeFileSync allows you to open files in external applications or run custom scripts. However, when sandboxed as Flatpak, external applications or scripts from your host system are not accessible. If you want to give FreeFileSync access to your host applications/commands, run this command in terminal to give it access to your session DBus:
flatpak override --user --socket=session-bus org.freefilesync.FreeFileSync
(Or you can use Flatseal to configure this permission).
Now you can run any app/command, if you prefix it with "flatpak-spawn --host", i.e.:
flatpak-spawn --host mycommand arguments
How to install FreeFileSync
- Click Download — the developer's official website opens in a new tab.
- Download the latest version there and run it. Choose Custom/Advanced where offered, and skip any bundled extras.
- Prefer the command line? With Flatpak you can install and update it with: flatpak install flathub org.freefilesync.FreeFileSync
- Open FreeFileSync once it finishes installing.
