Executable Files

To free hard disk space, you can delete executable files for accessories and games that you don't intend to use, for example the CD Player accessory or Freecell game. To remove accessory or game files and their corresponding online Help files, delete the files using the Windows NT Setup program.

For more information about removing executable files for accessories and games, see "Adding and Removing Windows NT Components" in Chapter 12, "System Maintenance with Windows NT Setup," in the Windows NT System Guide.
