Part 4 How to scan iTunes?

iTunes, as a free and easy-to-use music application, it is loved not only by Mac users, but also by Windows users. Same as the Mac version, iTunes for Windows also saves the music files into a Media folder, so if you want to delete the duplicate music files, you need to import the Media folder into Cisdem for scanning.

Tips:

Cisdem will only help you remove duplicate songs from the Media folder, if you want to completely delete those duplicate songs, please reference the sentences below:

1. Why can I still play those deleted music files after deleting them with Cisdem?

The duplicate music files are removed to Recycle Bin by default, and iTunes can automantical trace those deleted music files in the Recycle Bin when you play them in iTunes, so you need to permanently remove them from Recycle Bin if you don't want to play them in iTunes any more.
