Before you can begin to examine the different features of Project, you will need to create projects. A project is the file type most commonly used with Project. The file extension is .MPP. Each project you save or open will most likely be an .MPP file when dealing with Project. Each project you create will be its own file. This chapter covers the basic tasks associated with creating, opening, and working with Project at the project level. This includes creating projects from scratch and building them from templates.
