When I want to move/export multiple files or even folders to other apps (for example to unpack some zip/rar/7z/etc. files) I would have to do this for each individual file separately. With something like 10 files or a folder containing that amount of files, it is practically guaranteed that one or more files get missed. The currently available actions (deleting selected files, moving them within Proton Drive and making them available offline) are very limiting.
