You can play the contents of subdirectories, but you can't traverse an entire tree using just automatic file advancement. That is, if I had a tree that looked like: /music/song1 /music/song2 /music/folk/chant1 /music/folk/chant2 /music/song3 I could switch to /music and play song1, song2 and song3, but I'd have to actually move to /music/folk before I could play chant1 and chant2. Hope that helps. -Brian
