The following options are available to you:
R Normal Track Sequence
The tracks are played in the normal order
(e.g. track 1, 2, 3, etc.).
In MP3

mode, the track order is determined
by the order in which the tracks are written
to the MP3 data carrier when it is created.
Alphabetical order is the most common.
Once all the tracks in a folder have been
played, the tracks in the next folder are
played.
R Random Medium
All the tracks on the medium are played in
random order (e.g. track 3, 8, 5 etc.).
R Random Track List (MP3 mode only)
You hear the tracks of the current track list
or the currently active folder (including all
subfolders) in random order.
i The Normal Track Sequence option is
automatically selected when you change
the disc you are currently listening to or

option is selected, it remains selected after
COMAND is switched on or off.

Multisession CDs
For multisession

CDs, the content of the first
session determines how COMAND will
process the CD. COMAND plays only one
session and gives priority to the audio CD
session.
If possible, use COMAND to play only CDs
that have been written in one session.
File structure of a data carrier
When you create a disc with compressed
music files, the tracks can be organized in
folders. A folder may also contain subfolders.
The disc may contain no more than eight
directory levels. Files beyond the eighth level
will not be recognized by the system.
Track and file names
When you create a disc with compressed
music files, you can assign names to the
tracks and folders.
COMAND uses these names accordingly for
the display. Folders that contain data other
than MP3 or WMA tracks are not displayed by
COMAND.
If MP3 or WMA files are stored in the root
directory itself, the root directory will also be
treated as a folder. COMAND will then show
the name of the root directory as the folder
name.
You must observe the following when
assigning track names:
R track names must have at least one
character.
R track names must have the extension
"mp3" or "wma".
R there must be a dot between the track
name and the extension.
Example of a correct track name:
"Track1.mp3". Audio
