If you create 2+ projects the structure looks like:
/[destination_folder]
-[project-name1]
--backblue.gif
--fade.gif
--index.gif
--index.html
--...
-[project-name2]
--backblue.gif
--fade.gif
--index.gif
--index.html
--...
-backblue.gif
-fade.gif
-index.html
-project-name1.whtt
-project-name2.whtt

The top level index contains a list of all the projects
The project index.html contains a list of all the urls in a project.
Both of these autoforward down if there is only one at that level.

The whtt's allow you to open a specific project for updating by clicking on a
filename.
