If you are building an AutoPlay compact disc title, you can copy the Autorun.inf file in the root directory of the DirectX 3 SDK compact disc to the root of your application directory. This text file contains the following information:
[autorun]
OPEN=SETUP.EXE
If your application's setup program is called Setup.exe, you will not have to make any changes to this file; otherwise, edit this file to contain the name of your setup program. For more information about the Autorun.inf file, see The Autorun.inf File.
