SUMMARY Sweeper should erase thumbnails in x-large and xx-large folders. Those folders are created by kde applications (e.g. gwenview) and respect freedesktop specs (see https://specifications.freedesktop.org/thumbnail-spec/thumbnail-spec-latest.html#DIRECTORY) STEPS TO REPRODUCE 1. Open sweeper and select option to swipe thumbnails 2. Push the « clean » (don't know its exact name, it is « Nettoyage » in French locale) 3. Type « ls -aR ~/.cache/thumbnails » in konsole OBSERVED RESULT x-large and xx-large directories have not been emptied EXPECTED RESULT x-large and xx-large directories should be empty SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: arch linux (available in About System) KDE Plasma Version: 6.0.5 KDE Frameworks Version: 6.2.0 Qt Version: 6.7.1 ADDITIONAL INFORMATION Looking at the privacyfunctions.cpp file on the github repo, it seems (I am not a programmer, could be wrong) that it should be easy to fix just by adding a few lines.
