I am trying to scan all my playlists in the settings menu but won't succeed.

I have a tree with subdirs and ultimately a directory for each disc. This directory will contain the song files and 1 m3u8 playlist for the disc.

I don't understand why foobar won't find all my playlists when given the Music directory that contains everything.

When given this same directory all my songs are found.

On the other hand when giving the complete path to a cd foobar will show the corresponding playlist.

Is there a way to scan the whole tree for playlists or do I need to put all my playlists in a single directory?
