I asked similar question in Qt for Symbian group, but perhaps this is better place.
It is possible to synchronize playlists between the PC and the Symbian phone (over USB/MTP with WMP).
When synchronized, the playlist files (*.pla) are copied to "Playlists" folder, but as soon as the USB cable is disconnected, the playlist files disappear, but the Music Player on the phone still sees the playlists. I assume they copied to some database (MPX?).
Is there any "official" way to list all the playlists on the device and access them? GalleryModel in QML would be one, but it does not support playlists in Symbian. Any other way? Native Symbian API?
