Class DuplicateFiles

public class DuplicateFiles
extends java.lang.Object

This class is used to identify Duplicate files that iTunes creates when iTunes is set to keep the music folder organized. As of version 9 iTunes contains this setting in Edit > Preferences > Advanced > Keep iTunes Media folder organized. Duplicates are found by inspecting file names for iteration counts. If no duplicates are in a folder than a track might be named "01 Track.mp3". If there are duplicates of Track that iTunes created they will be named "01 Track i.mp3" where i is the number of that duplicate.
