If all the mp3s are in one folder click on the second one and them scroll down to the last. Press and hold the shift key and click the last one. Now right click and chose delete.
im not that great with computers. i know enough to really mess them up. im running windows xp home on a toshiba laptop with an intel pentium M .98 gig of ram and a 1.5 gig processor. i need some help getting rid of all of these duplicate songs. ive been deleting them manually or so i thought with my iTunes for months. is there a simple to use program or way to delete the duplicate song and still leave one song of the duplicate soi can still listen to it???? i currently have 165 gigs of music to go through and im guessing half of it is duplicate, triplicate or even more.
