I copied two disks to the sd card in the kn7000.
I looked at the directory structure.
In the rootdirectory there is a subdirectory Private. In this directory you have one directory technics, and in this one you have a directory Kn7000.
In the directory kn7000 is a file called kn7000Mn. I think this one is important..
In the directory kn7000 you have all the disks that I copied...in this case 2 directories called tfld001, tfld002.
I suppose technics folder 001 and 002.
I tried to copy another disk from my pc to the cardreader and I named the disk tfld003.
The kn7000 couldn't see this directory...it's all a matter off editing the file kn7000Mn...but how.
