What is a QTZ file?

QTZ files mostly belong to Quartz Composer. QTZ files are used by Quartz Composer to store compositions that drive dynamic visuals on macOS.
They store settings in the property list (plist) format, which contains the instructions and parameters for rendering animations and visual effects.

These files define how graphics, video, or interactive elements behave.

They are primarily utilized in Apple development environments.
