Going to free up some disk space in your Linux desktop and/or mobile device? Try cleaning leftover data by your Flatpak apps.
Flatpak is getting so popular in Linux today, that it’s hard to avoid installing applications via Flatpak package. Some Linux Distributions, such as Linux Mint 21 and Fedora 38, even include flatpak packages in their Software Manager/Gnome Software.
After removing Flatpak apps, there may be useless data (e.g., run-time libraries and personal data) left in your system. Advanced users can remove them by running flatpak uninstall --unused and flatpak uninstall --delete-data command. However, a stupid simple graphical app can be helpful for those hate Linux commands.
Flatseep, a free and open-source GTK4 application, is the tool to do the job removing useless data after removing Flatpak app packages. Which, can be useful to free up some disk space and/or remove sensitive data.
Depends on how many Flatpak apps you installed/removed, and how long your system is running with them, it can free up from few MB up to more than 1 GB space.
As you see in the screenshots, the app is quite easy to use. Simply click “understood” warning, that only appear in the first launch. Then, it automatically detect the amount of leftover data and provides a “Clean” button. Just click on that button and done!
The application is written in Python programming language, with GTK4 and LibAdwaita toolkit. So, the UI looks good in Ubuntu, Fedora, etc with GNOME Desktop and follow system color scheme that switch between light and dark mode automatically. As well, it should work in mobile devices, such as PinePhone.
