Explorer allows you to create links to Adobe PDFs and to PDFs' bookmarks. When creating a link directly to a PDF's bookmark, you can link to the default bookmark type, which is a "go to a page view" type of bookmark. If a linked PDF contains bookmarks, the bookmarks are stored in a Bookmarks folder for the PDF. If a link goes directly to a PDF bookmark, in the Links tab of the Explorer dialog you will see the PDF's file name, followed by the bookmark's name.
