I have some old photos encrypted with boxcryptor saved in Onedrive, so I just reinstalled the boxcryptor app and tried decrypting but nothing happens. I get that warning popup that decrypting is not neccessary but then nothing happens. Copy pasting files do a local drive just leaves me with the encrypted files.
I also downloaded my security key and tried with a local account but that results in the same.
One strange thing is that the file endings are .bc.7z and not just bc. Looks like they were zipped with 7z after the bc treatment but I don't think I did that. Any hints are appreciated.
