I changed the file association for my .dvdmedia files on my Mac to point at Blu-ray Player Pro. As it turns out this was a mistake as it turned all the .dvdmedia files into plain directories. Google has shown me the usual cmd-I solution (which doesn't work because what were bundles are being viewed as directories because of the file association on .dvdmedia) and some outdated advice to try duti which unfortunately doesn't compile on High Sierra (and might not work at all, who knows?). Presumably there's some way to fix this by editing a plist somewhere, but I've not found it yet. I did find that logging in as a different user showed the files correctly. Any thoughts on how to undo my gross mistake?
The association with public.iso-image is what I would like to have for dvdmedia.
Update: I was able to change the association in the .plist file and have it stick by logging out and back in again, but the .dvdmedia files still show as directories rather than single files. There must be something more than this one plist that is causing .dvdmedia files to be incorrectly displayed... I really don't want to have to re-rip the DVDs that I've put on my hard drive if I can avoid it.
Update 2: I tried moving
Preferences.old and logging out/back in. STILL have folders instead of bundles.
