Palm Address Book Archive (ABA) is a legacy file format developed by Palm, Inc. for the Palm OS mobile platform. This format functions as a structured container for exporting and backing up contact information, including names, telephone numbers, and physical addresses, from handheld devices to desktop synchronization software. As an obsolete specification, it carries minimal security risks, though it has largely been replaced by modern standards like vCard following the discontinuation of Palm hardware.
