Simply download two asp files and place them in any IIS directory. By default, the starting directory is C:\Inetpub. When you execute the index.asp in browser you can see all files and folders from your C:\Inetpub, listed in a neat format. You very well can browse through the entire file system. You can also change the location by just modifying the method, buildTree(). Modify the line, appendThings("C:\\InetPUB\\", 0);

You can download the code. Unfortunately there is no live demo of this code for security reasons. This zip file contains two ASP pages and a image folder, which contains some images. If you want to work with the index.asp, then you need to have all these images.
