.YYZ File Extension

GameMaker Studio is a video game development program available for Windows, macOS, and Linux. It allows developers to create 2D video games, using drag-and-drop programming and the GameMaker scripting language. Developers can then publish their finalized games for play on a variety of platforms.

Typically, GameMaker Studio projects are saved as a directory that contains a YYP file (which defines the project's layout and included assets) and several sub-directories (which contain the project's assets, objects, and other data). However, developers can also export a GameMaker Studio project as a single YYZ file. This Zip-compressed file contains all the project's data, packaged into a single archive for easier storage and sharing.

How to export a GameMaker project as a YYZ file

To export a GameMaker project as a YYZ file:

1. Open the project in GameMaker.
2. Select File → Export Project → YYZ.
3. Name and save your YYZ file.

NOTE: In version 2.3, GameMaker began saving YYZ files in an updated format. Thus, YYZ files created by versions 2.3 and above of GameMaker cannot be opened in versions 2.2 and below.

You can open a YYZ file with YoYo Games GameMaker. Doing so will allow you to view and edit the game development project your YYZ file contains. To open a YYZ file with GameMaker:

1. Select File → Import Project.
2. Navigate to and open your YYZ file.

If necessary, you can also decompress a YYZ file with any Zip-decompression utility, to extract the files it contains. Before doing so, you may have to rename the YYZ file to use the .zip extension.
