Multisession CDs
For multisession CDs, the content of the first
session determines how COMAND will proc-
ess the CD. COMAND plays only one session
and gives priority to the audio CD session.
If possible, use COMAND to play only CDs
which were writte ninone session.
File structure of a disc
Whe nyou create a disc with compressed
music files, the tracks can be organised in
folders. Afolder can also contain subfolders.
A disc can contain amaximum of 255 folders.
Each folder can contain a maximum of 255
tracks and 25 5subfolders. Adisc can contain
a maximum of 4,000 tracks.
The disc may contain no more than eight
directory levels. Files beyond the eighth level
will not be recognised 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 which contain data other
than MP3 or WMA tracks are not displayed by
COMAND.
If MP3 or WMA files are stored in the highest
directory itself, the highes tdirectory will also
be treated as a folder .COMAND will then
show these directory names as folder names. You must observe the following when assign-
ing track names:
R
track names must have at least one char-
acter.
R track names must have the extension
"mp3" or "wma".
R there must be a full stop between the track
name and the extension.
Example of a correct track name:
Track1.mp3

sion "m4p".
i If, as well as MP3 files, there are music
files in these audio formats stored on the
disc, loading may require longer before the
first track is played.
i The MP3 audio encoding method is under
licence from Fraunhofer IIS (Institut Integ-
rierte Schaltungen –Institute for Integrated
Circuits) and Thomson.

Gracenote ®
Media Database i
This function is only available in audio CD
mode.
There is a version of the music recognition
software from Gracenote ®
, Emeryville, Cali-
fornia, USA on the hard disk. You will notice
this by the logo which can be seen in the bot-
tom right-hand corner of certain audio dis-
plays. Many audio CDs contain CD text. COMAND
uses the information contained therein to dis-
play the artist, albuma nd trackname. If the audio CD does no
tcontain any CD text
information, COMAND can use the Gracenote
Media Database to identify unknown audio
tracks when running in audio CD mode. This
is only possible if the relevant information is
saved in the Gracenote Media Database and
if the "Gracenote Media Database" function
is activated.
If this is the case, COMAND will display the
available data such as artist, album and track
name in the relevant displays and lists.

Database when reading an audio CD, you will
