First off, what player do you have? I know this is the Fuze board, but many new people cross-post so we can’t assume that’s what you have.
Secondly, how did you put the audio books on there in the 1st place, where were they from and what format were they?
You should be able to open up Windows Explorer and navigate to them (or any file remnants) and delete them. They will not show up in your Playlists folder as they are not playlists.
