Where does the Apple app Contacts store its files in Mavericks? I'm making a clean re-install of Mavericks on a client's computer. I believe she had a large number of address book entries in the Contacts app that were not in iCloud, and I need to restore them from the backup. Where are they stored? I'm guessing they should be in Users/~/Library/ but I cannot find the location.
Contacts.app stores its data in ~/Library/Application\ Support/AddressBook.

For the individual databases, you can list them using the following command:

find ~/Library/Application\ Support/AddressBook/ -name "AddressBook-v22.abcddb"
