Creating a playlist containing all filename filters

[KimboNo1]

I have thankfully entered the wide-world using MusicBee... and I am I have made the move.

My issue is that I would like to have a playlist that contains all playlists. From what I see when I am attempting to create such a playlist is that there is no 'filename' that is available so as to customise one playlist.

Would someone kindly tell me what criteria settings I should be using

Thanks

create an auto-playlist that either sources its files from playlists you choose or create a playlist folder and any playlists in that folder will be consolidated when you select that playlist folder
