Get Rating from my Sansa Fuze / Encrypted data on MTABLE:SYS

hey there. I want to save all the ratings I did using the fuze on my pc.

How can I do that? In MTABLE.SYS there seem to be only tag data (path, filename, album, artist, title, tracknumber). and some encrypted data (data which actually looks random to me).

So I’d like to know where to find the ratings. Maybe there is even a tool which can access them?!

And what kind of data is stored in the encrypted parts of MTBALE.SYS?!

Thank you
