72 AudioMP3 CD operationFile structureWhen creating a MP3 CD, you can organize 
MP3 tracks into folders. A folder can also 
contain additional folders.
 
A CD may have a maximum of 255 folders 
in total.A maximum of 255 tracks are permissible 
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.
 
Track names and folder namesWhen creating an MP3 CD, you can assign 
names to the MP3 tracks and folders. 
COMAND uses these names in MP3 mode 
for the corresponding display.Please note the following when assigning 
folder and track names:
Track and folder names must contain 
at least 1 character.
Track names may contain up to either 
thirty or fifty characters depending on 
the CD format. If a name exceeds this 
character limit, COMAND will not be 
able to display it in full.
Track names must have the extension 
“mp3”.
A period must appear between the 
track name and the file extension.Example of a correct track name: 
Track1.mp3
Empty folders or folders containing data 
other than MP3 or audio CD tracks will not 
be displayed by COMAND.
