About MFK files
An .MFK file is primarily a plain-text game mission script used by The Simpsons: Hit & Run. These files store parameters that dictate mission objectives, manage asset loading, and trigger in-game reward definitions. Beyond gaming, the .MFK extension is also used as a proprietary data file for Méga-Fric accounting software, and as a magnetic susceptibility data container generated by the AGICO MFK1 Kappabridge laboratory instruments.
Because the game-based .MFK format is essentially a proprietary text script, it can technically be opened using standard text editors like Notepad++ or Visual Studio Code. However, the format is highly restrictive. Outside of specific modding environments or specialized scientific hardware, the file is entirely useless to the average user. Sharing an .MFK file with a colleague who lacks the original game engine, modding tools, or AGICO software will result in an unrecognized file error, and modern IDEs do not provide native syntax highlighting for it.
To overcome these limitations, conversion is highly recommended. For game modding and collaborative editing, convert .MFK to standard TXT or XML files so they can be easily version-controlled on platforms like GitHub. If you are handling AGICO scientific data or accounting databases, converting the data to CSV is essential for statistical analysis in Microsoft Excel. Just drag and drop your file here to analyze and convert it - free, online, and without installing software.

The MFK Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our MFK converter.
