What is a MPP file?

Files with the MPP file extension are files that have been created with the Microsoft Project software application. Microsoft Project was the third application ever released by Microsoft and was first introduced in 1984.

The Microsoft Project application is used for the tracking, organization and progress of projects for both business and personal use. It allows users to control schedules, workload, finances and other project elements.

Microsoft Project is now included with Microsoft's Office Suite as of the 2010 version of Microsoft Office.
