GMC 2008 Acadia - Manual (Page 251)

• Create a folder structure that makes it easy to find
songs while driving. Organize songs by albums
using one folder for each album. Each folder
or album should contain 18 songs or less.
• Avoid subfolders. The system can support up to
eight subfolders deep, 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.
• Make sure playlists have a .m3u, .wpl or .pls
extension as other file extensions might not work.
• Minimize the length of the file, folder or playlist
names. Long file, folder, or playlist names, or
a combination of a large number of files and folders,
or playlists could cause the player to be unable to
play up to the maximum number of files, folders,
playlists, or sessions. If you wish to play a
large number of files, folders, playlists, or sessions,
minimize the length of the file, folder, or playlist
name. Long names also take up more space on
the display, potentially getting cut off.
• Finalize the audio disc before you burn it.
Trying to add music to an existing disc could
cause the disc not to function in the player.
Root Directory
The root directory of the CD-R or CD-RW disc is treated
as a folder. If the root directory has compressed audio
files, the directory is displayed 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.
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.
No Folder
When the CD-R or CD-RW disc contains only
compressed files, the files are located under the root
folder. The next and previous folder function does
not function on a CD-R or CD-RW that was recorded
without folders or playlists. When displaying the
name of the folder the radio displays ROOT.
