I've been trying to figure out how to store and playback my flac and mp3 files using a memory stick. I picked up a 1tb Sandisc stick and loaded the files as ArtistName/AlbumName/Track. Most of the Artists played up to Ramones. I thought perhaps if I put the files in folders, Rock, Jazz, Classical and so on, that might help but only the Rock folder was visible with those artist. None of the other folders or files appeared. The file system is exFAT. Any help will be appreciated.
