Create directory?

I have my mp3 files on drive e and want my playlists on drive d.

Is it possible for mp3tag to create directories upon creating the playlists?

I'm trying to do the following on the playlists:
D:\Music\%artist%\%album%.m3u

I get an error saying the list couldn't be created.

Indeed, MP3Tag does not support variables on M3U creation. Would be a nice feature to add.

Yes. I'll add this to a future release of Mp3tag.

Best regards,
