KDE Manjaro, reverting app associations to default settings


I’ve toyed a little bit around my install and I installed a game via AppImage. It prompted me to choose a default application to open that file type, and I choose AppImage Settings (it was the only one available) and selected to remember it, thinking that AppImage Settings app is the same as AppImage Launcher.
However, now a lot of filetypes are messed up, e. g. .html, .tar, ,mkv, etc. I don’t know all the file types that got changed, so I’d like to revert the associations to defaults. Is there a possibility for that or do I need to reinstall the system?

Thanks in advance,

Just checked, most of the extensions are switched to open by default with AppImageLauncher Settings

  1. If it’s just one file association, the easiest way to delete it is to:

    kcmshell5 filetypes

    and then check there and delete.

  2. If a lot, it’s easier to copy the mime files of a USB stick that you just burned the ISO to:

    cp --recursive /USB/usr/share/mime /PC/usr/share/mime

    where USB and PC denominate where you mounted the USB or PC exactly.
