Four Easy Ways to Open GMD Files

The scenario: You have a file with the GMD file extension on your computer that you need to open. You double-click it as usual, expecting for a program to load it up, but sadly nothing happens. You try it again, but still nothing happens. What can you do? Try these four easy methods to open a troublesome GMD file.

1st Method: Open it in another program.

When you double-click GMD files, your computer attempts to open it in a program associated with GMD files. If there’s no program associated with GMD files on your computer, the file won’t open. To open the file, download one of the most popular programs associated with GMD files such as Great Budget Model Definition for the Template, IMAGINE Graphical Model, or Game Maker Stored Game Under Development.

2nd Method: Take a hint from the file type.

The GMD file extension usually indicates it's under the umbrella of Developer Files. However, if it’s another file type, it might not open with one of the programs listed above. Take the following steps to find the file type:

  1. Right-click the file.
  2. Click “Properties” (Windows) or “More Info” (Mac).
  3. Locate the file type under either “Type of File” (Windows) or “Kind” (Mac).

3rd Method: Check with the developer.

So you’ve tried using a different program, you’ve confirmed the file type, and your GMD file still won’t open. Even if these methods were unsuccessful, you might still be able to reach out to a software developer for help.
