What is .M3G File Extension?

M3G is a file extension used by Mobile 3D Graphic files. These are multimedia files commonly used by some Nokia mobile phones, particularly the Nokia Series 40 series and other Nokia models that do not use the Symbian operating system. M3G files are most often used for 3D games or screen savers utilizing the Mobile 3D graphics format.

M3G, also known as Mobile 3D Graphics API, allows Java ME developers to get access to a higher library level, making it possible to manage and render 3D scenes and objects within the application or game. It is a 2ME Optional Package that enables three-dimensional (3D) graphics to be run at interactive frame rates on mobile and other resource-constrained devices.

How to Open .M3G Files?

To open M3G files, all you need to do is double click on the file and your device will automatically check the file extension to try and identify what type of file it is.

But if your file extension is not recognized by the device, you will receive the following message on Windows:

Windows can’t open this file:

File: file.m3g

To open this file, Windows needs to know what program you want to use to open it. Windows can go online to look it up automatically, or you can manually select from a list of programs that are installed on your computer.

  1. On you’re computer, open Control Panel > Control Panel Home > Default Programs > Set Associations.

  3. Choose the program you installed on the list.
  4. If you did not find the program from the list, right-click on the M3G file, then click Browse.
