Say for example reasons your main save directory is C:/Documents and Settings/User/Desktop/Downloads/Limewire Downloads

Maybe LW could sort your specific downloaded file types into different directories.......

Audio
C:/Documents and Settings/User/Desktop/Downloads/Limewire Downloads/Audio

Video
C:/Documents and Settings/User/Desktop/Downloads/Limewire Downloads/Video

Pictures
C:/Documents and Settings/User/Desktop/Downloads/Limewire Downloads/Pictures

I think you get the idea... Just a suggestion.
