The files are present in the "actions" folder in my Mp3tag installation, but they're not appearing in the program itself when it's run. How can I make Mp3tag see them?
see this thread for possible storage places:
Also, see the program installation folder.
Ah, I'd been extracting the files to "Program Files (x86)\Mp3tag", not "AppData\Roaming\Mp3tag". Funny that, it used to work all the time in the former directory.
