.MPX File Extension

An MPX file contains a compiled menu for a program developed by Microsoft Visual FoxPro, a database creation and management program for Windows. It stores information about the appearance and functionality of a menu that is included in the user interface (UI) of the program. MPX files are compiled from an .MPR file, which stores source code that defines the properties of the menu.

File exported by Microsoft Project, a project management application; saves the project plan in an ASCII text format instead of the .MPP binary format; designed for exchanging project data between different versions of Project as well as with third-party programs.

Several third-party programs can export and import MPX files. The MPXJ Java library can be used for implementing MPX import and export functionality in third-party applications.
