I think that I will restate my question above in a way that isn't so strange.
I am trying to put some mp3 files on my LinuxMCE core. The songs are on a usb flash drive that is recognized as a hardrive. How do I move the mp3 files to to my hardrive?
You have a number of options. You could plug the flash drive into a PC on your home network an the mount the share from your Core and copy the files over to your Core's /home/public/data/audio directory. Alternatively you could plug the flash drive directly into your Core and then go to the KDE desktop of your Core and copy them over from there. LMCE expects audio content to be stored in artist/album directory structure.
