look...LimeWire is NOT a server based supplier of files...end of discussion...hence, there is NO url for the location of any files that may, or may not, be on the Gnutella network...

once you have downloaded a file, it is on YOUR computer, and hence I would have to assume you would have to upload it to the server that hosts your 'space'...and please note, since said file is probably copyrighted, then it is probably against the law to host it on your 'space'
