What is an .ABCDP file?
.ABCDP is Address Book CoreData Person File
Backup metadata file created by Address Book, a contact organization application bundled with OS X; contains a property list for an Address Book data card entry with information about a person.
When Address Book is opened, ABCDP files are used to build or rebuild the SQLite database, which is used for quick searching. The files also enable address searching within the Mail and iChat applications, which are integrated with Address Book.
ABCDP files can be found in the following directory:/Library/Application Support/AddressBook/Metadata
NOTE: The ABCDP format was introduced in OS X 10.6. In OS X 10.8, the Address Book application was replaced with the Contacts application.
