Windows Tips : Ever wondered about making a folder without name?

Ever wondered about making a folder without name? Windows don't allow it, but I have a trick for it.

(1) Rename any folder, and erase everything.
(2) Now, hold "Alt" and press 0160.(from your numpad,)
(3) That's all. If you wanna make more nameless folder in same directory,proceed for...
Alt+01600160
Alt+016001600160.. (repetition of 0160)
