Buick Automobile User Manual page 226

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.
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.
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.
3-98
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:
•
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.
