I would of expected the tracks to automatically appear in the walkman, so I would suggest you update the software and try again.However,you should be able to add all the tracks from the File manager to the Walkman by creating playlists: Media--Music--Playlists--New playlist--Add--OK--this will return you to the File manager where you can mark and add your music tracks to create playlists in the Walkman.Let me know what happens.
