Playlists in MediaMonkey are created in the MediaMonkey database and shown in the Playlists node in the Media Tree. If they're missing there they would've been deleted and unless they were exported manually there would not be a way to recover the Playlists.

Hello,

I recently created two new playlists and now for some reason, they are not coming up? Any suggestions and advice on how to get them back would be appreciated.

Thank you!
