iTunes Library Check

iTunes Library Check is a software that thoroughly scans your iTunes library to find any unlisted files in iTunes. It works by cross-checking your iTunes music library and checks if the discovered files are referenced in the iTunes xml file. The software is efficient in its function, listing all references that lack actual files under the "Missing files" tab view and all unreferenced files under the "Extra files" tab view.

However, the software comes with a warning: The Move selected to Trash feature cannot be undone, and it will permanently delete files from their original location. Therefore, users should be careful while using this feature.

The software requires users to have their music folder set to the default location in ~/Music/iTunes/. Additionally, users need to have the default usage of iTunes, which means "Copy files to iTunes Music folder when adding to a library" enabled and keeping the library consolidated.

Overall, iTunes Library Check is an excellent software to verify and maintain your iTunes library's integrity. It is user-friendly, efficient, and ensures that all files in your iTunes library are accounted for.
