My Clip+ is running in MSC mode. Under Kubuntu Linux I connect to it and see the expected folders. At one time I created a folder within Music called Playlists as an experiment and placed in it a playlist called Classical 2. Although the Classical 2 playlist was detected by the Clip+ and showed up in its Playlists list, the playlist was empty. So I deleted that Playlists folder. Unfortunately the Classical 2 playlist still shows up on the device even though it isn't visible anywhere in the drive view when I plug the Clip+ into the laptop.
