What are LAY files and how to open them

What is a LAY file?

LAY files have multiple uses, and DVD Studio Pro Project is one of them. Read more about the other uses further down the page.

DVD Studio Pro Project

The .lay file extension is frequently found on files created using the Apple DVD Studio Pro. DVD Studio Pro is a high-end software tool published by Apple. It allows users to produce DVD primaries that will serve as the master disk for software replication in the mass production process.

The .lay file format contains metadata internal to DVD Studio Pro and the DVD project and is typically stored within the VIDEO_TS directory of a DVD project.

Please note that .lay files are just the layout of the project and not the project itself. It is the 'blueprint' of the project and is not to be included in the projects when burning them to disk.

The DVD Studio Pro software has been discontinued.
