When you put in the link to your document in VSD the 'Link' box will popup. At the bottom of the box select 'Document' and put your link in there. VSD will grab your pdf and upload it.
The Edit/Add files option is used to add files to your web site that may not be directly linked from VSD. Such as if you add a slider. You put the code in VSD where the slider will appear, but the pictures themselves will have to be uploaded separately along with several .js files. You can upload these yourself, or Add them to your VSD site and when you publish your site they will be uploaded.
Graphics for the web, email, blogs and more!
