Root Directory The root directory of the CD-R or CD-RW is treated as a folder. If the root directory has compressed audio files, the directory is displayed as the CD label. All files contained directly under the root directory are accessed prior to any root directory folders. However, playlists (Px) are always be accessed before root folders or files. If a disc contains both uncompressed CD audio (.CDA) and MP3 files, a folder under the root directory called CD access all of the CD audio tracks on the disc. When the CD contains only playlists and compressed audio files, but no folders, all files are located under the root folder. The folder down and the folder up buttons search playlists (Px) first and then go to the root folder. Order of Play Tracks recorded to the CD-R or CD-RW are played in the following order: • 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. 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. The empty folder does not display. • Play begins from the first track in the first folder and continues sequentially through all tracks in each folder. When the last track of the last folder has played, play continues from the first track of the first folder. When play enters a new folder, the display does not automatically show the new folder name unless you have chosen the folder mode as the default display. The new track name displays. No Folder When the CD contains only compressed files, the files are located under the root folder. The Sc (previous) and next c Tfolder functions do not display on a CD that was recorded without folders or playlists. 3-99
