Orphan Pages
Pages within a project are usually linked to each other. 

Pages that are not linked by any other page within a project are referred to as orphan pages.

To view the orphan pages click on the 'Browse Project' tab in the toolbar and choose the  'Orphan Page' option.


  


Pages displayed in the orphan pages list can also be moved to other projects or deleted.
Select the check box for the pages you want to move or delete, and click on the move page or delete button respectively.
