OutJob files are a type of file in Altium that allow designers to easily and repeatedly generate outputs from their design. It is very configurable and can group different outputs into one container so they can all be generated with one click. More can be read about it here on Altium's docs: https://www.altium.com/documentation/altium-designer/streamlining-generation-of-manufacturing-data-with-output-jobs

You can create an OutJob file by right clicking on the project in the Projects panel and navigating through "Add New to Project" > "Output Job File" as shown below
