FreeFileSync
Free folder comparison and sync tool with the same look and the same job it does on Windows.
Our verdict
FreeFileSync is the rare case where the Windows app you already use simply carries on. The developer builds a Linux version from the same code, so the two panes, the compare button and the sync button are where you left them.
Two small catches. The download on the official site is a compressed archive rather than an installer, so most people are better off getting it from Flathub, an app store built into Ubuntu and Fedora. That Flathub listing is put together by volunteers rather than the developer, and the page says so plainly.
Your saved jobs move across, but any path that starts with a drive letter needs pointing at the Linux folder instead. Check one job with a small folder before you trust it with the family photos.
What's good
- The Linux build is made by the same developer, so the window and the settings match the Windows one
- Your saved sync jobs carry over, so an existing backup routine keeps working
- The base version is free and open source
What to know first
- The official Linux download is a compressed archive rather than a tidy installer, so the Flathub listing is the easier route
- The Flathub listing is packaged by volunteers rather than the developer
- Extras such as parallel copying and the auto updater are held back for people who donate
- Drive letters in old job files need repointing to Linux folder names
