The zip file above is an archive file, a container for other files.
When you download it and double-click on it, it will extract a folder.
Inside the folder are two Scrivener files. One is a basic Scrivener document with the essay structure elements as described in the videos. The other is a Scrivener template file which you can import into Scrivener as a template. This allows you to select the template from the template chooser when opening a new Scrivener file.
These files were created for the Mac version of Scrivener. I don't own the Windows version, but the elements can be easily recreated in the Windows version of Scrivener.
