Hi - I'm using the 'Case conversion' action, but I've changed it so that it applies to the \_DIRECTORY field. (Which is just the MP3's parent folder.)
MP3tag correctly ignores any folders with the correct capitalisation, but if it finds a folder that does need changing, it successfully sorts out the first one, but then it bombs out.
A couple of times the Case conversion worked properly, but I can't work out what conditions are needed to guarantee failure!
Attached is the error log.
Any ideas? Cheers,
Richard
