All known file formats using extension .LAY

While Advanced Layouter Project is a popular type of LAY-file, we know of 9 different uses of the .LAY extension. Different software may use files with the same extension for different types of data.

DVD Studio Pro Project

The .lay file extension is frequently found on files that are 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 software 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.
