The "Hyperlinks" section of HelpNDoc's project analyzer lists all hyperlinks found throughout the project. The hyperlink analyzer can be used to:

Filtering broken links

Broken links point to a specific topic which has been deleted since the link creation. HelpNDoc's project analyzer makes it easy to spot broken links by clicking "Filter" then "Show broken items only". This will filter the view to display only broken links. By double-clicking a link in the view, or selecting it then clicking "Locate and select", the topic containing the link will be shown in HelpNDoc's main window so that the link can easily be corrected.
