How to open GMK file?

The most common problem when using Game Maker Project Format is that a specific GMK is not associated with the program. Thus, when you open GMK, the program selection wizard or some other program starts. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the GMK file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Game Maker

The first step is to check if the computer has the Game Maker program installed. To do this, enter the name Game Maker into the system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file GMK with Game Maker. Below you will find a list of applications that support GMK files.

Programs to open GMK file

Remember to download programs supporting GMK files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Game Maker with GMK files

If, despite the installed application, the GMK file does not start in the Game Maker application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. Information about the file and the program that the file is associated with are available here. Changes can be made using the "Change" button. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. The "always use the selected program ..." field will set the Game Maker application as the default for handling the GMK file.

Step 3. Update Game Maker to the latest version

The fault may also lie with the Game Maker program, it is possible that Game Maker Project Format requires a newer version of the program. This can be done using the application (if it provides such options) or from the YoYo Games website and install the latest version.

Step 4. Check for the following problems with the GMK file

Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:

The affected file may be 0 KB or smaller than expected. Usually this applies to GMK files downloaded from the Internet in case the download did not finish properly. Downloading the file again should fix the problem.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the GMK file that we want to open. As a result of the scan, sometimes it is not possible to recover GMK files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the GMK files changes over time. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for this. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged GMK files. The easiest way to restore the file is from a backup or by contacting YoYo Games, but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted GMK files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. These directories are write-protected to them and it's very hard to fix this problem. It is best to move GMK to a different directory.
This problem usually affects more complex files. In this case, the GMK file is blocked by the first application to open it. Closing other programs should help. Sometimes you have to wait for the session to the file GMK to close. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If the problem persists, restart the machine.
