Visual folder comparison and synchronization
  12 reviews

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.

Voilà un programme de synchonisation de fichiers très fonctionnelle. Plusieurs options de mise-à-jour synchro entre deux dossiers. La copie miroir entre deux médias est vraiment excellente. Logiciel backup-synchro à recommander !

The Graphic User Interface (GUI) simply sucks. It doesn't adapt proportionally to the display size. Bring that back to the drawing board. That's too bad because I used the Windows version and it was absolutely flawless.

For straight to Ex HDD it's fantastic. Very simple to use once you get it and super fast! Actually faster than Linux trying to copy files. Do however download from the website, it's a much smaller package and later versions.

For Flathub instance, I'm not sure what to dislike more - 500 MB space required for installation, or, share-points (SMB) not recognized.

As others have said, this version doesn't recognize SMB network locations. Version 10.7, downloaded directly from works great.

Excelente para sincronizar seus arquivos sem estresse. Junto com RealtimeSync fica mais automatizado ainda. o unico porblema é ele não "ver" as network shares, para usar uma unidade de rede tive que montar a pasta compartilhada usando CIFS

I just needed it to sync a folder on my hard drive with a folder on my USB storage. It worked perfectly for that so I'm happy with it.

Can't get this Flatpak version 9.8 to recognise a Windows share. It doesn't 'see' existing network shares, so I've reverted to using the .deb version direct from the Freefilesync site. The program itself is fantastic, but this Flatpak implementation is not good.
