Folder named "CON" cannot be created on XP, Windows

Did you know ? Folders with name: CON, PRN, AUX, CLOCK$, NUL, COM1, COM2, COM3, COM4, COM5,
COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, & LPT9
cant be created using Windows Explorer or Command Prompt directly!

( Try this out.. right click on your desktop and try creating folder named "con"it changes back to "new Folder" )

This is prevented as XP terms these folders as SYSTEM Folder Names reserved only
for the Operating System.. But there is a backdoor..(this trick is to create
system folders on XP through command prompt )

Try this:

Syntax:md \\.\\$path
Example:prompt>md \\.\\C:\con
Explanation: This would create a folder named "con" on your "C Drive"

Similarly to delete such folder:
Syntax:rd/s \\.\\$path
Example:prompt>rd/s \\.\\C:\con
Explanation: This would remove the folder named "con"!
Note: rd(Remove Directory) command is used with "/s" switch as otherwise it
would give error that "folder is not empty"!

On another hand...if you ever wondered how to create a folder with no
name...then try this:

Create a New Folder from Windows Explorer
Select rename & type: "ALT+255"(Use Numpad)..thats it!
ALT+255 stands for blank character in it still accepts your folder name!
