These are not templates. Bearly the design of the screen layout in xml format (you can use Notepad or Word to edit it if you want to). The only way to do a template is to export it. Go to Library, Tools, Screen then select to Export or Import. The file saved by MagicInfo has extention filename.scp you can then copy that file to your computer, and then Import it.
The filename.scp file has all the content and the design of the screen.
