After you have d/led a file it is on your computer all you have to do is find it.... it more than likely will be in the folder that limewire's default is.

I think the right path is:
C:\windows\shared <---- this is the default
type this in the adress bar of your Internet Explorer, or Windows Explorer.... both will work

if you changed the folder to where you save stuff you can find out what folder it is by going to "Tools" then "Options" on your Limewire Client
