The Quicken Address Book is a proprietary database format developed by Intuit for use within its personal financial management software suite. This format stores user-defined contact information, mailing addresses, and payee details linked to specific financial transactions. As a legacy format largely replaced by integrated database structures in modern iterations, it presents minimal security risks and is primarily encountered when migrating historical records from older versions of the application.
