HeLp: iTunes & LimeWire
 

I made a folder i clicked export library full of videos[from itunes]the itunes file appears in the folder but when i look in limewire the folder has nothing in it ...?someone tell me

A little confused. Export from where? LimeWire or iTunes? iTunes export function is only for playlists. BTW the LW media player, whilst it can open playlists from other audio programs such as iTunes, it can't play videos. ;)
Likewise, you can't add videos to the LW playlist. LW's media player & playlist function is only designed for audio files.
