A Working File is a type of file attachment you can add to your Records that contain extra materials like project files or isolated audio stems that can help people remix your Records.

You can add them to your Records by uploading them in the Working File widget of the Record upload process.

You can also add a Working File to a Record you've already uploaded by clicking the "Edit" button and following the steps.

Note: Working Files are totally optional, but are definitely recommended to add to Records that include layered files you may have created in Photoshop, Pro Tools, or After Effects.
