ITDB files are an extension compatible with iTunes and Apple’s operating systems. The developer is Apple. These database format files store information about multimedia files. ITDB files were first used with iTunes version 8. ITunes got a “Genius” feature for organizing and recommending files. Genius uses ITDB databases to save data. The data is stored in SQLite format. SQLite is a database system with SQL support. ITDB extensions are used by two Apple operating systems, Mac OS and Windows. It is common for these iTunes databases to have the ITDB extension. There are around 403 other files with this extension too. Some may be used harmfully as malware, so caution opening unknown ITDB files is wise. To open ITDB files, use iTunes. Conversion to other formats is not possible.
