Why not refresh your media with the pc power and not the mp3 player?

Rock box have a good solution, and I can adapte that, rockbox is open-source, I can make my version of it… What I’m trying and (maybe) can do is create a solution that not uses the firmware directly. Using the pc to change the library files can be possible, so as make the mp3 not do the refresh… Changing the firmware is not a solution to me, is a sugestion only.
