How do I unmask a folder which was previously masked by a virtual folder called "Desktop"?

I tried to change my desktop folder from D:\test4 to D:\test5:

In the last step, I didn't move the files from D:\test4 to D:\test5.

So what happens is that in D:\, I have a total of 2 virtual folders, both called Desktop:

1. 1 virtual folder Desktop which masks (and points to) D:\test5

2. 1 virtual folder Desktop which masks (and points to) D:\test4

Now the contents of D:\test4 is no longer showing on my desktop, however it is still being masked by a virtual folder.

Obviously since D:\test4 is now no longer my Desktop folder, I was trying to make it go back to being a "normal folder" (i.e. not masked).

I was wondering how do I unmask it?

Delete the desktop.ini file (it's hidden by default) in test4 and the "Desktop" name will be gone.
