Start Command Prompt. (Start->Run->cmd)
Type attrib "filename or folder with complete path" +s +h
For Example, if the folder you wanted to make super hidden was located at C: and folder's name is 1234 then the path is C:\1234. You type "attrib C:\1234 +s +h" without the quotes.
 

The folder properties will not allow anyone including you to make the folder visible in case you try to.

The folder made super hidden cannot be made visible as the hidden property is grayed out.

Use [ Start->Run] to access~
             Type attrib "filename or folder with complete path" -s -h  to disable superhidden~
