Managing Files
When the user chooses the Save or Save As menu command, you usually write to a file the data that the user has entered in the active window. When the user selects a file using the Open command, you read information from a file. You can use the File Manager to read and write files. You can use the system software routines provided by the Standard File Package to present a standard and consistent interface to the user when saving and opening files. See the chapters "Introduction to File Management" and "Standard File Package" in Inside Macintosh: Files for information about these topics.
