Jim,
You can turn on Directory Indexing in IIS for a given folder. It can
be dangerous for obvious reasons, but you can do it. It is also just a
black and white page, so if you want a look and feel for it you will
not get it.
To make it a little more secure you could create a page which will give
you the file listing for given folder. Use the Request.PhysicalPath to
get the location of a folder and create a DirectoryInfo object for that
folder. Then iterate the Files collection and show links for the
extensions you want exposed. You could produce a decent looking page
this way with filtering on the allowed extensions.
