The publication folder
Select any publication from the list of publications and click on its folder icon in the first column. The sample document Hyper.Net Features is a good choice because it contains a little of everything. The selected publication folder for your selected publication will open. Your screen should look something like this:
Within the publication folder is a list of Topic folders. At the top of the list you'll see all the Topics belonging to the Rich Hypertext rendition. Near the bottom you will see Topics associated with the additional published renditions (Source File, HTML and PDF). At the end of the list is an XSL file containing the "breadcrumb". This file is used to programmatically display a hyperlink list of the user's current location within a publication and also to compute the current location of your application.
