Permissible file systems
The permitted file system is
ISO9660/Joliet for CD-R and CD-RW.
Multi session CDs
With multi session CDs, the content of the
first session determines how COMAND
treats the CD. For example, if the first session contains
data in audio CD format and the second
session contains data in MP3 format,
COMAND will treat the CD as a conven-
tional audio CD.
File structure

MP3 tracks into folders. A folder can also
contain additional folders.
The root directory may have a maximum of
255 entries in total. (folders or tracks)
A CD may have a maximum of 255 folders
in total. A maximum of 255 tracks are per-
missible per folder.
Mathematically a maximum of 65025
tracks would result. However, this amount
is usually not reached since MP3 requires
approx. 1 MB storage per minute recorded.

CDs, software and hardware for writing
audio data to CDs are widely available.

Problems may be encountered during
playback of user-written CDs with a
storage capacity of more than 700 MB.
These CDs do not meet valid standards
