Each label folder contains two page style documents. The name and location of the page style documents are constructed as follows:
<LabelDocuments setting>\<label name parameter>\Page-<document type parameter>.doc
As you can see in the picture above there are page style documents for the document types Letter and Overview. The prefix Page- is a fixed value.
When settings are taken from the template documents at runtime, all other contents of the documents are ignored. This means that only the page setup properties are taken from the page style template document and only the style information is taken from the style sheet template document. All other contents, like text, images, tables, header, and footer contents are ignored.
