Getting files from another computer
 

I no longer have access to a computer that I downloaded all my files to. Is there a way to find them on the network and transfer them onto my new computer?

If you know the ip address of the computer and it has limewire running you could try to direct connect to it.

If not then you'll probably have to redownload everything, which is what you'd be doing anyway;).
