We already learned about the file types PowerPoint 2011 for Mac can save. But when you go and look at the file types that PowerPoint 2011 can open, you'll find that the list of file types is not exactly the same. Several file types may be common. When you access the Open dialog box in PowerPoint 2011, you can choose the file type you want to open (see Figure 1).
