MPX File Format

What is an MPX File?

An MPX file is a project management data file used by Microsoft Project, primarily for importing and exporting task and resource information. This format allows users to share detailed project plans between different versions of the software or with other tools that support it.

Key Features of MPX Files

  • Data Import/Export: MPX files are designed for transferring tasks, resources, and schedules across various platforms.
  • Compatibility: They can be used in older versions of Microsoft Project (up to 2013) but are not supported in newer versions like Office 365 or later editions.
  • Structure: The file format is structured with specific records that define project details such as start dates, finish dates, resource assignments, and more.

How to Open an MPX File

To open an MPX file, you need a compatible software application. Here are some common methods:

  1. Microsoft Project:

    • Use Microsoft Project versions up to 2013.
    • Import the MPX file into your project by selecting “File” > “Open” and choosing the MPX file.

  2. Alternative Software:

    • Other project management tools that support MPX files can be used as well, such as OpenProj or GanttProject.
    • These applications allow you to import and export data in the MPX format for compatibility with older Microsoft Project versions.

Common Issues When Opening an MPX File

  • Lack of Supporting Software: Ensure you have a compatible application installed on your system.
  • Corrupted Files: If the file is damaged, it might not open correctly. Try to recover or recreate the file if possible.
  • Virus Infection: Scan the file for viruses before attempting to open it.
  • Insufficient Permissions: Make sure you have the necessary permissions to access and open the MPX file.
  • Outdated System Drivers: Ensure your system drivers are up-to-date, especially those related to file handling.
