The best way is to create a new project, either using the New Bareboard Project wizard ( File > New Bareboard Project ) or with a stationery template. This sets up a project for you, including all the default options and library files. Then add the existing files used for Cosmic to the project (for example, through drag and drop from the Windows Explorer, or right-clicking in the CodeWarrior Projects view and selecting Add Files ). Ensure that the new project uses the same memory model and CPU type as the Cosmic project.
