What is a QTZ file?

A .QTZ file is a Quartz Composer Data file.

QTZ files store compositions made with Quartz Composer. This visual programming language, created by Apple Inc., is used to construct interactive graphical user interfaces and visual elements for various applications across different platforms.

The data held within a QTZ file describes the layout, appearance, and interactions of its composition. It's common to use .qtz files for creating interactive visuals such as animations, transitions, and other effects.

These .qtz files are editable using the Quartz Composer editor. The customised compositions can then be exported for use in other programs or on the web.
