Remember when you format memory like a hard drive you erase everything. Move music to your internal mp3 memory and do a profile - folders should appear.
If you have flashed your player with the firmware update you can get 520 songs on the player for both internal and external combined but be warned that if you exceed this count your player will start to forget the earlier loaded songs - listed but not addressable (playable). The same is for the folder count eg. add album = artist + ablum title (min 2 folders). Plus always profile your songs after loading new music or deleting as this is an index build process to play song 152 = title x. This includes accidental radio recordings to MP3s.
