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.
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.
i
COMAND supports up to 50,000 files
from one data medium. For data media with
more than 64 GB, only files in the following
folders are supported: music, pictures, vid-
eos.
Track and file names
When you create a disc with compressed
music files, you can assign names to the

If MP3 or WMA files are stored in the root
directory itself, the root directory will also be
treated as a folder.
You should observe the following when
assigning track names:
track names must have at least one char-
R
acter.
track names must have the ending of a
R
