During this website development, I have found myself looking for a solution to see my website's directory tree as a local disk via Windows File Explorer.
The solution I have found is very easy and requires no special software.
Just to notice that the solution was verified using Windows 7, but I guess it will work the same using Windows XP.
Here are the steps:
1. Open File Explorer
2. Select from the menu Tool --> Map Network Drive
3. At the window opened (above) click the "Connect to a Web site that you can use..." link.
4. The next steps are straight forward.
