Why can’t we Create a Folder by name CON

I am sure that many people still don’t know that they can’t create a Con folder in windows XP and in some other Operating System.

So Why cannot we create a folder by a name Con? What’s the reason behind it?
It’s pretty simple, Con is a reserved name from the early days from DOS, it stands for the “CONSOLE” I/O device, Since it is already used by the system. If we create one with some evil tricks then the system will get confused. There will be an ambiguity.
Check out other reserved words to understand what are all the reserved words using which you can’t create folders in windows.
Like Con, many other reserve words are there which we can’t create. They are
PRN – It stands for printer.
AUX – It stands for Auxiliary device.
COM0, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9 – They stands forserial ports.
LPT1, LPT2, PRN – They stands for Parallel ports.
NUL - It stands for Bid Bucket.
Did I said that the Con folder can’t be created, what a big typo. Well friends, There’s a evil trick to create a Con folder. Here goes the evil tricks.
Create a new folder. Name it Con and press Alt + 255 simultaneously.
Well Alt+255 stands for a blank character in ASCII so it allows you to use this folder name.
Note:- Actually you’ll have to press the number’s of the number pad or else it won’t work. That is, create a new folder, rename it Con but don’t press enter yet. Hold down Alt and type 255 on the number pad and then press enter. (for laptop users, press Fn key and press the letter keys k-i-i to make use of number pad).
The next time when someone asks the question that why can’t we create a folder by name Con, say with confidence that it is not true…
