The CD player is able to read and play a maximum of 50 folders, 50 playlists, and 255 files. You can change playlists by using the previous and next folder buttons, the tuner knob, or the seek buttons. Long file names, folder names, or playlist names may use more disc memory space than necessary. To conserve space on the disc, minimize the length of the file, folder or playlist names. You can also play an MP3 CD-R that was recorded using no file folders. The system can support up to 8 folders in depth, however, keep the total number of folders to a minimum in order to reduce the complexity and confusion in trying to locate a particular folder during playback. If a CD-R contains more than the maximum of 50 folders, 50 playlists, and 255 files, the player will let you access and navigate up to the maximum, but all items over the maximum will be ignored. 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 will advance to the next folder in the file structure that contains compressed audio files and the empty folder will not be displayed or numbered. No Folder When the CD-R contains only compressed files, the files will be located under the root folder. The next and previous folder functions will not be displayed on a CD-R that was recorded without folders or playlists. When displaying the name of the folder the radio will display ROOT. When the CD-R contains only playlists and compressed audio files, but no folders, all files will be located under the root folder. The folder down and the folder up buttons will search playlists (Px) first and then go to the root folder. When the radio displays the name of the folder the radio will display ROOT. Root Directory The root directory of the CD-R is treated as a folder. If the root directory has compressed audio files, the directory will be displayed as F1 ROOT. All files contained directly under the root directory will be accessed prior to any root directory folders. However, playlists (Px) will always be accessed before root folders or files. 3-116
