Right-click on any .3gp file and select Open with > Choose another app. Tick the box for 'Always use this app to open .3gp files'. Scroll down and pick VLC from the list, if it's not there click on 'More apps' at the bottom of the list. It should be in that list, but if not you can click 'Look for another app on this PC' and browse to find vlc.exe.
That is odd, it should be there.
.3gp is missing, and there's no option to reset this list or to add/remove items from it:
That's not working, says preferences were reset because of some error.
Of course that works, what I would like is to restore the ability to associate .3gp to any program from Windows Settings. As far as I know Windows itself doesn't offer this capability.
Yes Windows does, but .3gp file type has to show up in the list of file types before you can associate it with a program and it doesn't for you. I do not know if these file types are native Windows (meaning that they are installed with the operating system) or if they are populated by VLC. From what you posted in post#8 that is not the only file type that is missing. That's why I suggested uninstall and reinstall VLC to see if it would populate all the file types it can open. Restart before reinstall.
3gp? isnt that for the Software Guitar Pro?
No, it's the video format for older Nokia phones when they had Symbian S60 and alike. But maybe other apps also use the same extension for other unrelated formats.
