In the expanded archive there should be a file with the extension .mcp. This is the project file that CodeWarrior uses to store all its information on the program. Double-click on this file in Windows Explorer and it should launch the CodeWarrior IDE. The IDE displays a Project window, which shows the source files and libraries that the demo program uses. You can try building the project, or opening the files in the editor and studying the source code. HTH.
