trying to create a virtual directory with IIS 7.5 Express/WebMatrix

ASP.NET

I have created a web application where a user can upload files from the UI. The web app saves the file to a file system and saves the file name and path to a database table. I am using the Casini dev web server but I need to turn my C:\UPLOADED_FILES\ directory into a virtual directory so I can open the files through the web app. I have performed the following steps to set this up:

1. Select "New Site" > "Site From Folder" from the main menu in WebMatrix
2. Select C:\UPLOADED_FILES\ from "Browse For Folder" dialog
3. WebMatrix displays "The Site UPLOADED_FILES has started successfully" in the status bar

However, when I right-click a file in the directory structure in the left panel and select "Launch in Browser" the following message is displayed "IIS 7.5 Express Detailed Error - 404.20 - Not Found".

What's the problem here? Am I missing a step?
