When it comes to creating junction points, the only Microsoft utility designed for the task—a command-line tool called Linkd. However, I recently discovered an undocumented method in Windows XP for manually creating junction points without the need for the Linkd. This undocumented method simply involves creating a specially configured Desktop. Another big trap is that you can indeed delete the folder acting as the junction point from within Windows Explorer or from the command line with the Del command.
However, rather than just deleting a junction point, these commands can actually delete the target directory and all subdirectories. So it's extremely important that you use the steps in this article when it's time to remove or change your junction points.
You might also notice that the Dir command reports odd free-space statistics on drives that contain folders acting as junction points.
In a previous article, I showed you how to use reparse points along with the CurrentWork technique. Since this example technique really helps to bring home the goals achieved by using junction points, it's worth taking a moment to briefly recap the CurrentWork file-management technique. The main advantage of using junction points is to reduce the amount of time and effort you spend navigating your hard disk in both Windows Explorer and in your application's Open and Save As dialog boxes. For example, the target folder could have the path:.
As I finish an assignment, I remove that junction point and create a new one for the next assignment. Of course, this means that the target folder is always changing as I move from assignment to assignment. This has saved me an immeasurable amount of time and frustration. Once you learn how easy it is to create your own junction points, you can apply this example to the way you work.

I tested this behaviour a couple of times, installing different software applications and updates, so that I presume that it does not depend from the actual software that is being installed, but from the installer itself, that cannot manage a junction point for the "Installer" folder.
