How to open GMX files

Did your computer fail to open a GMX file? We explain what GMX files are and recommend software that we know can open or convert your files.

What is a GMX file?

GMX files are GameMaker document/object files, which you can read more about below.

The GMX file extension indicates to your device which app can open the file. However, different apps may use the same file extension for different types of data. So a GMX opener may not be able to open all kinds of GMX files. In this case, though, we only know of one specific use.

GameMaker document/object

Through our analysis of GMX files, we know that one use of the format is GameMaker document/object . We have not yet described in detail what these files contain and what they are used for, but our team is working tiredlessly through thousands of file formats. We'd love hearing from you if you have information about the format.

We have not verified any programs yet that works with this specific format. If you know any, please use the 'Suggest a program' link below. Thanks!
