Extract text from MFK files
To convert your MFK file to another format, you need The Simpsons: Hit & Run or other Game software.
To convert other file formats to the "Mission Definition File" file type, you need software like The Simpsons: Hit & Run or a similar tool.
The .MFK file extension is a chameleon, most famously serving as the Mission Framework script for the cult classic The Simpsons: Hit & Run. In this context, the file functions as a plain-text directive list that initializes levels, loads assets, and defines mission logic (e.g., level.mfk). While these files are technically human-readable, the proprietary extension causes friction; Windows does not natively recognize them, and opening them in rich text editors like Microsoft Word can introduce formatting errors that crash the game. Modders typically need to treat these as TXT files to safely edit game parameters.
Beyond gaming, the extension appears in scientific laboratories using AGICO Kappabridge instruments, where it stores magnetic susceptibility measurement data. These files are often legacy binary or proprietary text formats that are inaccessible to standard analysis tools. For these users, converting data to CSV or XLSX is essential for visualization in Excel. A third, rarer variant involves data files for the legacy Méga-Fric accounting software. For archiving these diverse formats, converting to PDF ensures the code or data remains viewable without the original environment.
Convert.Guru analyzes your MFK file, detects the exact format, and lets you read the text inside.
Users also converted IRC, BCH and DLG files.

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.
