iScan - Find and delete duplicate songs in your iTunes library

4 posts in this topic

A little app I made because I hate having duplicate songs on my iTunes, and with 2000 songs I'd hate to find them myself. Shockingly, my script found 20 duplicate songs and I saved 82.5MB worth of space.

My script uses a decent comparison method, so some song names that might not be equal might still be picked up. After scanning your library, please uncheck any songs that you do not wish to delete and afterwards click Delete Selected.

iTunes is needed to run the application

#include <GUIConstants.au3>
#include <GUIListView.au3>

Global $listcount = 0, $foundCount, $Found, $iTracks, $Tracks ;some variables that will be used
$GUI = GUICreate("iScan - Delete duplicate songs", 283, 306, 193, 125)

_GUICtrlListView_SetColumnWidth($List1, 1, 87)
