Notes about the GMD file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The GMD file type is primarily associated with 'Game Maker' by YoYo Games Limited. Game Maker allows you to make computer games, without the need to write a single line of code. You can make games with backgrounds, animated graphics, music and sound effects, and even 3D games. Game Maker was written by Mark Overmars. He is a full professor at the Institute of Information and Computing Sciences at Utrecht University in the Netherlands. On Feb 28 2007 version 7.0 of Game Maker was released through the YoYo Games website.
