For macOS 10.10 or later. This application will list the file paths of the media files in your designated "iTunes Media" folder which are not in iTunes' track library. Additionally, you can select a different parent folder and its contents will be compared to the iTunes library. Includes options to Filter results, Add a selection of found files to iTunes, move them to the Trash, and Export a text file listing the file paths. Mobile apps information is not accessible.
Also see Find Empty iTunes Media Folders.
The original name of the "iTunes Media" folder was "iTunes Music". That's why this script is named the way it is.
These files are in my "iTunes Media" folder but do not appear as track entries in iTunes. The tracks may have been deleted from iTunes but, for whatever reason, I did not choose to move their files to the Trash.
