| | |  | | | Inside Macintosh: Files This document describes the parts of the Mac OS that allow you to manage files and other objects in the file system. It shows how your application can handle the commands typically found in a File menu and provides a technical reference to the File Manager. This document describes the hierarchical file system (HFS) used by the Mac OS but does not cover the Mac OS Extended format (previously known as HFS+), which became available with Mac OS 8.1. Note that Chapter 3 documents the Standard File Package (used for specifying the names of files to be opened or saved), which is superseded by Navigation Services. | | | | |
