Leopard Reference: Cocoa
File management consists of storing persistent information on a physical medium and retrieving that information later. Cocoa provides several programming interfaces for gaining access to stored files, folders, and disc recordings. Developers can also create and display dialogs that solicit choices from users when they are opening and saving files.
