Apple iTunes database
File type: Various data file
The itdb file extension identifies an internal iTunes database file. It stores library information in an SQLite database rather than containing the actual media.
These files belong to an iTunes library and are normally maintained by iTunes.

Apple iTunes creates itdb files in its library folder to store information about media and other library items, including songs, sounds, videos, podcasts, and iPhone, iPad, and iPod apps. The files use SQLite database format.
Two files commonly created by iTunes use the itdb file extension: iTunes Library Extras.itdb and iTunes Library Genius.itdb. The Genius database supports Genius playlists and music recommendations.
The format was introduced with iTunes 8, the first iTunes version to include the Genius feature. iTunes for Windows and older versions of iTunes for Mac use these files; newer macOS versions use separate Music, TV, and Podcasts applications instead of iTunes.
itdb files are internal iTunes library databases, not documents intended for direct opening. Apple iTunes for Windows can read them when they are in the correct iTunes library folder. Older versions of Apple iTunes for Mac can do the same on Mac OS X or macOS.
Do not edit or move an itdb file while iTunes is using the library, because doing so can damage the library database.
An itdb file cannot be meaningfully converted as a standalone file. It is an internal database used by iTunes, and its contents are not a media format.
To transfer library information, use iTunes to export the library as an XML file where that option is available. Individual songs or videos must be exported or converted separately from the library database.
