Why does the player display less internal memory than the volume it 
indicates? 

Cause and solution: 

-

 

The volume that the player indicates is the memory volume of the flash within the 
player. And a player must conserve firmware for work, which occupies some 
memory of the flash.   

-

 

The firmware is system files of the player which cannot be seen and revised by the 
user.  

-

 

The internal memory displayed by the player does not include the volume of the 
firmware. Therefore, it will be less than the volume it indicates.
