Guides for USB downloader management program

What is the reason of  non-constant compressing ratio in the voice 
download mode? 
VBR files vary the amount of data stored depending on the 
complexity of a particular section of music, therefore the 
compressing ratio is relatively smaller when compressing complex 
music like classic, pop, etc. 
 
 
Why is there quality difference between directly compressing CD 
music and compressing by MP3 ? 
MP3 is lossy compression method; it compresses with discarding 
the inaudible sound. This method cannot preserve the exact CD 
sound source, so the quality of sound compressed with MP3 is 
worse than directly compressing CD music. 
 
Can I save the file that is not music one? 
It can be saved on the audio card, but not uploaded for protect 
copyright. And already saved file(s) cannot be changed.
