With Duplicate Music Files Finder you can track your music files duplicates and delete them. The program uses advanced search techniques to detect duplicates(it searches MP3s TAGS, detects duplicates even if the file names are not the same etc). If duplicates are dound you can delete the files you want. Just select them and press the right mouse button. You can also play the selected files in Winamp to see if they really are duplicates (Winamp must be installed).
