A template file is any file living below the layouts directories of either the project or any of its theme components incudling partials and shortcodes.

The function is particulary handy with dynamic path. The following example ensures the build will not break on a .Type missing its dedicated header partial.

{{ $partialPath := printf "headers/%s.html" .Type }}
{{ if templates.Exists ( printf "partials/%s" $partialPath ) }}
  {{ partial $partialPath . }}
{{ else }}
  {{ partial "headers/default.html" . }}
{{ end }}
