Nameless Folders

I really dont see a reason why people would want to do this, but while surfing the net, I stumbled upon this trick with which you can actually make folders nameless. I have tried numerous times to do it entering nothing while renaming it, but it always was set back to the older name, no matter what

The trick goes like this:

1. Select the folder to be renamed

2. Press F2

3. Press ALT

4. While pressing ALT, on the numlock keypad (NOT the character keypad) enter 0160

5. Press Enter, and there you have a folder without any name

I wonder if there was actually a use of it .... Hmmmmmmm
