Open MPI File

The .mpi file extension has multiple uses and could represent different types of data depending on the application being used. This article will cover some of the possible formats and ways to open these files.

Message Passing Interface (MPI)

The .mpi file extension is primarily associated with Message Passing Interface (MPI), a standardized and portable message-passing system designed by a group of researchers from academia and industry to function on many parallel computing architectures. The system is widely used for high-performance computing.(source)

MPI programs can be written in different languages like C, C++, Fortran, Python etc. These .mpi files contain source code written to be run on parallel computing architectures. A free, high-quality, and widely-used implementation of the MPI standard including this and many others is provided by MPICH2 and Open MPI.

These .mpi files can be opened on any text editor like Notepad, Notepad++, Atom, and so on. Most Integrated Development Environment (IDE) software like Microsoft Visual Studio, Eclipse and PyCharm can also be used to open and edit these .mpi files.(source)(source)

Magix Music Maker 16 Project File

The MPI file could also be a Magix Music Maker 16 Project File. These files hold music projects created with the Magix Music Maker, a software application for composing and recording digital music. In this case, .mpi files would contain the music tracks, digital beats, tunes and all other music-associated details of the project.(source)

The only software that can open this version of .mpi file is its associated software-MAGIX Music Maker. But newer versions of Magix Music Maker may sometimes fail to open older .mpi files due to compatibility issues. Hence, it's good to keep a version of the software that was used to create the .mpi file.(source)

MPI File Important Information

As we've seen above, .mpi files can serve different purposes, so it's essential to consider the context to successfully open and use these files. Trying to open an MPI file in the wrong software can lead to read and format errors.

For MPI files associated with Magix Music Maker, ensure you have the correct version (or an updated one) of the software. It's also important to remember that an .mpi file of a particular type can't be converted into another by just changing the file extension. Doing so would lead to data corruption.
