Screw the Security

Have you ever tried to create a folder named: 
-CON
-PRN
-AUX
-NUL
-COM1
-COM2
-COM3
-COM4
-COM5
-COM6
-COM7
-COM8
-COM9
-LPT1
-LPT2
-LPT3
-LPT4
-LPT5
-LPT6
-LPT7
-LPT8
-LPT9

in Windows OS?

If YES, Why you even bother going here?

If NO, It's because a pop-up message will appear saying "Specified device name is invalid" the after closing the pop-up box your folder name will return to it's default name, New folder. CON is a reserved word in the Windows and the underlying DOS system. I'll teach you how to create a folder named "CON".

1.) Go to command prompt
2.) Type in prompt (FOR EG. TO CREATE CON FOLDER IN E: DRIVE)
     C:\>md \\.\e:\con
3.) To delete the folder use the following command
     C:\>rd \\.\e:\con
NOTE: The folder can only be deleted in the Command Prompt. 
4.) Voila! You're done. Have fun with your folder named CON / con.
