ASP.NET Special Folders

ASP.NET defines several Special folders.

When a new Web site is created the App_Data folder is created by default.
It can contain a SQL Server 2005 Express Edition database, another database, or an XML data file that will be used in the Web site.

These folders are protected by ASP.NET
For example, if a user attempts to browse to any of there folders
(except App_Themes)
User will receive an HTTP 403 Forbidden error.
