Different people have iTunes set up their own way. But if you do have iTunes set to copy all added songs to its own library then you can delete the songs from the LW Downld folder after they have been added.
But don't get confused with the LW Playlist that shows in iTunes. Ignore that. Those songs are the ones in your LW download folder & can be played but not copied from that playlist.

thanx...

itunes does NOT have option checked to copy song to itunes. i had originally "assumed" it was because of the dupes but it is not. i have checked myself.

the playlist i understand and it would not be 3 plus gbs in size in the itunes folder are actual files sorted by itunes default routine which i may add is very organized . these files are duplicate files of just about half of her share/save folder (same) in limewire. as i have posted my one concern is killing the dupes without changing her itunes. i think i pretty much covered it all in posts. although sometimes my posts can be a bit long

again thanx to you for mentioning the above.
