Saving and Opening with Different File Formats

A file format is an arrangement of data in a file that specifies the file type and defines the file in a way that enables any application that can open the file to open it correctly. When you create and save a regular project file, it’s saved as an MPP file. The file name’s .mpp extension indicates that this is indeed a regular project file.

However, you can save project files in other file formats. You can also open files with other file formats in Microsoft Project. Table 29-1 details the file formats supported by Microsoft Project for saving, opening, or both.
