Root Directory The root directory of the CD 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) are always accessed before root folders or files. 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 the folder mode has been chosen 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 next and previous folder functions do not function on a CD that was recorded without folders or playlists. When displaying the name of the folder the radio displays ROOT. 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 searches playlists (Px) first and then goes to the root folder. When the radio displays the name of the folder the radio displays ROOT. 3-94 File System and Naming The song name that displays is the song name that is contained in the ID3 tag. If the song name is not present in the ID3 tag, then the radio displays the file name without the extension (such as .mp3) as the track name. Track names longer than 32 characters or four pages are shortened. The display does not show parts of words on the last page of text and the extension of the filename is not displayed.
