Document templates contain reusable text styles, graphics, and layouts, giving you a file that's ready to go from the moment you open it.
Affinity Photo allows you to create (export) document templates, which typically contain placeholder content and text. Templates have a .aftemplate file extension.
When saving a template, a preferred set of defaults will be saved with it. Text attributes, object properties, stroke/fill color, guides, as well as grid setup, and more can be associated with a template.
