Yeah, I figured it out now, thanks. The problem I had was trying to put the config folder onto an exFat disk, that doesn't seem to work.

So, I found out you can manually set the directory with all the config files for Deluge by adding the -c argument when running the program. It's been discussed here https://forum.deluge-torrent.org/viewtopic.php?t=43397 for example, and is also touched on the FAQ: https://dev.deluge-torrent.org/wiki...
