I have just set up a separate FLAC library for my Yamaha NP-S2000 streamer. Until now I only had a library of MP3 files.

I would like to remove all MP3 files from my Mezzmo library and add the FLAC files only. Both file types are maintained in separate directory trees. The MP3 files represent the standard Windows 'music' library.

Now when I go to 'Maintain Library' to delete the MP3 folder and the list of directories is empty despite the Mezzmo library has all the MP3 files. Hence I can't remove the MP3 directory.

I tried to remove the 'All Music' smart playlist from Mezzmo's library tree but when recreating the 'All Music' playlist it did not provide an option to choose the directory - it always defaults to library\music.
