FWIW, I haven't found a sane way of representing an Empeg's contents in a Windows filesystem (no symlinks, and none of the playlist formats are nestable). I keep my music collection on a Linux filesystem, with playlists represented by symlink farms. This means I can rsync them to a remote location as a backup, and can use emptool's "upload -p -r" to put them on the player (er, except I don't do that, I use something more resembling Pim's mp3tofid thing).
