The gmz file extension is associated with GameMaker Studio, a game-development tool from YoYo Games for Microsoft Windows that allows users to create computer games without programming knowledge. It is used to package a complete GameMaker project rather than a finished game.
A gmz file stores the project's source and resources in a form that can be imported into GameMaker. The format is mainly associated with older GameMaker Studio projects; newer GameMaker projects normally use the software's current project format instead.
Open or import a gmz file in GameMaker on Microsoft Windows. In GameMaker Studio, use the project import function and select the file.
Compatibility depends on the GameMaker version that created the project. If the file does not import in a current version, use a compatible GameMaker Studio release.
A gmz file is a project archive, so it is not normally converted with a general-purpose file converter.
Import the file into a compatible version of GameMaker, then save or export the imported project in the format supported by that version.
