Creating CAB Files

file provides the following benefits:
S All application f iles are present.
S A partial installation is prevented.
S The application can be installed from several sources, such as a desktop
computer or a Web site.
Use the CAB Wizard application (CABWIZ.EXE) to generate a .CAB file
foryourapplication.
