What is an MJB file?

MJB files mostly belong to JobControl. MJB files are job instruction files used in different industrial and simulation systems.
They mainly fall into three groups:
  • Laser Marking Jobs: These files use an XML format to store instructions for laser marking processes. They work with specialized software such as JobControl from SIC Marking Laser Workstation. For more info, visit Trotec Laser.
  • MuJoCo Simulation Models: In this case, the file is a binary container that holds a physics simulation model used by the MuJoCo system. Check out MuJoCo for additional details.
  • Machine Job Files: These are XML-based files that carry job instructions for managing tasks in computer-aided manufacturing, as seen with systems like hyperMILL or WorkNC.
    • FilExt.com tips: To open an XML-based MJB file, you can use a text editor or the intended application. Binary MJB files, however, require the associated software to decode and work with the machine job data. Using the correct software is key to working with these files.

    How to open MJB files

    You need a suitable software like JobControl to open an MJB file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your MJB file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a MJB file directly in the browser:. Just drag the file onto this browser window and drop it.
