Hi.
I didn't get the emptool library source to compile under windows yet, at least not in the way I wanted it to compile. There are some facts about it available at my homepage
http://www-new.incase.de/framed/empeg/, namely in the programming section. If someone wrote a tool to get a specific FID as a file from the player (and I think someone did this already, just don't have the time to look for it right now), and - even more importantly - upload a file to a specific FID on the player (which is yet to be done AFAIK), it would be fairly easy to write a small C wrapper to those tools that downloaded the complete music database (MP3s included) from the player to a directory on your disc or to upload the whole directory back to the player.
