What is an ABCDDB file?

ABCDDB files mostly belong to Apple Contacts. ABCDDB files are used by Apple to store contact data. These files are structured as a SQL database, specifically using the SQLite engine, which is the same system behind many Apple Contacts implementations on macOS and iOS.
Data stored in an ABCDDB file includes names, phone numbers, and email addresses, among other details. The internal SQL structure makes it easy for the system to quickly manage and retrieve contact information.
