The player is able to read and play a maximum of 50 folders, 50 playlists, 10 sessions, and 255 files. Long file names, folder names, or playlist names could use more disc memory space than necessary. To conserve disc space, keep the length of the file, folder, or playlist name brief. MP3 CDs do not require file folders. The system can support up to 11 folders in depth. The depth of the folders should be kept down to make it easier while locating a folder during playback. All items over the maximum are ignored. No Folder If a CD has no folder, only compressed files or playlists are located under the root folder. The next and previous folder functions have no function on a CD that is recorded without folders or playlists. When displaying the name of the folder the radio displays ROOT. Order of Play Tracks are played in the following order: Root Directory The root directory is treated as a folder. If the root directory has compressed audio files, the directory displays as F1 ROOT. All files contained directly under the root directory are accessed prior to any root directory folders. However, playlists (Px) always are accessed before root folders or files. • Play begins from the first track in the first playlist and continues sequentially through all tracks in each playlist. When the last track of the last playlist has played, play continues from the first track of the first playlist. • If the CD does not contain any playlists, then play begins from the first track under the root directory. When all tracks from the root directory have played, play continues from files according to their numerical listing. After playing the last track from the last folder, play begins again at the first track of the first folder or root directory. When play enters a new folder, the display does not automatically show the new folder name unless the folder mode is chosen as the default display. See "DISP" later in this section for more information. The new track name displays. Empty Directory or Folder If a root directory or a folder exists somewhere in the file structure that contains only folders/subfolders and no compressed files directly beneath them, the player advances to the next folder in the file structure that contains compressed audio files and the empty folder does not display. 3-96
