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 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 }}

```
