What is a GM2 file?

GM2 files mostly belong to GameMaker Studio 2. GM2 files are not a single standard format. They serve different roles depending on the origin and the software that created them.
Consider these common uses:

Game Save File: This GM2 file is a GameMaker 2 save file that uses GZIP compression. It typically stores game progress or settings, as seen with some game titles like Heroes of Might and Magic III.

3D Model Geometry File: In other cases, a GM2 file contains 3D model geometry data. Such files carry vertex, edge, and surface information that can be imported into 3D applications like Autodesk 3ds Max or 3D GameStudio. They are used in design and visualization workflows.

Gerber (PCB) File: A smaller group of GM2 files is formatted as Gerber files used for printed circuit board design. These contain layer data and manufacturing instructions for PCB production and are compatible with tools such as Altium Designer.

FilExt.com tip: The extension is reused for different purposes. To open and view a GM2 file, it is important to know the context in which it was created and then use the proper tool: a game engine for a save file, a 3D modeling program for geometry data, or a PCB viewer for Gerber files.

How to open a GM2 file

You need a suitable software like GameMaker Studio 2 to open a GM2 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.

GM2 file format details:

The file format determines how the data is stored in the file. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. If there are problems opening a file, you must first determine the file format used. Below you will find our evaluation of the GM2 files:

The GM2 file extension is not common and includes different formats for the applicable programs. The following file formats are most commonly found in GM2 files:

45% of all GM2 files are based on the well-known GZIP file format. Gzip is a compressed archive file format. Gzip (GNU zip) is only capable of compressing a single file. They consist of unreadable binary data. Most of these files are 91 KB to 440 KB in size. This file type is based on cutting-edge technology. The file name AUTOSAVE.GM2 is characteristic of these files. Files like these have the following tags: hotseat.
20% of all GM2 files start with the magic bytes GMF2, which are always the first bytes of this file format. The contents of these files cannot be read by a human; only a computer program can interpret the data. GM2 files are between 14 KB and 55 KB in size. Several words can almost always be found in the files, e.g. GMF2, RAMP0000p and TOON. Examples of file names are LTRVB001.GM2. Files like these have the following tags: ltrvt.

The remaining 35% of all GM2 files are files with no common format, often e.g. zlib. These files are often connected to dancehall. If you want to find out what your GM2 file contains, drag and drop it onto this page.
