Creating CAB Files
The Windows CE operating system uses a .CAB file to install an applica-
tion on a Windows CE-based device. A .CAB file is composed of multiple
files that are compressed into one file. Compressing multiple files into one
file provides the following benefits:
• All application files are present.
• A partial installation is prevented.
• 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
for your application.
Creating Device-Specific CAB Files
Do the following to create a device-specific .CAB file for an application, in
the order provided:
1 Create an .INF file with Windows CE-specific modifications.
2 Optional Create a SETUP.DLL file to provide custom control of the
installation process.
3 Use the CABWizard to create the .CAB file, using the .INF file, the
optional SETUP.DLL file, and the device-specific application files as
parameters.
Creating an .INF File
An .INF file specifies information about an application for the CAB Wi
ard.
