+A template file is any file living below the `layouts` directories of either the project or any of its theme components including partials and shortcodes.
+
+The function is particularly handy with dynamic path. The following example ensures the build will not break on a `.Type` missing its dedicated `header` partial.
+
+```go-html-template
+{{ $partialPath := printf "headers/%s.html" .Type }}
+{{ if templates.Exists ( printf "partials/%s" $partialPath ) }}
+  {{ partial $partialPath . }}
+{{ else }}
+  {{ partial "headers/default.html" . }}
+{{ end }}
+```
