GM None Pontiac Aztek - Manual (Page 211)

If you wish to play large numbers of files, folders,
playlists, or sessions minimize the length of the file,
folder, or playlist name. You can also play an MP3 CD
that was recorded using no file folders. The system
can support up to 11 folders in depth, though, keep the
depth of the folders to a minimum in order to keep
down the complexity and confusion in trying to locate a
particular folder during playback. If a CD contains
more than the maximum of 50 folders, 50 playlists, 10
sessions, and 255 files the player will let you access and
navigate up to the maximum, but all items over the
maximum will be ignored.
Root Directory
The root directory will be 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.
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 contains only compressed files, the files will
be located under the root folder. The next and previous
folder functions will have no function on a CD that was
recorded without folders or playlists. When displaying the
name of the folder the radio will display ROOT.
When the CD 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.
Order of Play
Tracks will be played in the following order:
• Play will begin from the first track in the first playlist
and will continue sequentially through all tracks in
each playlist. When the last track of the last playlist
has been played, play will continue from the first
track of the first playlist.
• If the CD does not contain any playlists, then play will
begin from the first track under the root directory.
When all tracks from the root directory have been
played, play will continue from files according to their
numerical listing. After playing the last track from the
last folder, play will begin again at the first track of
the first folder or root directory.
