Opening an MPP File

What is an MPP file?

The MPP file type is primarily associated with Microsoft Project by Microsoft Corporation. With Project you can set up projects, keep project teams aligned, and track and analyze projects. Housatonic and KaDonk have free Project file viewers (registration may be required). OpenProj is a free Project program for multiple platforms and can read MS Project files.

How to open an MPP file

You need a suitable software like Microsoft Project to open an MPP file. Without proper software you will receive a Windows message "How do you want to open this file?" (Windows 10) or "Windows cannot open this file" (Windows 7) or a similar Mac/iPhone/Android alert. If you cannot open your MPP file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application.
