How to create CON folder in windows XP which others can't ! !...

Hello guys...

Many ppl dont know that they cannot create "CON" folder in windows.

Some ppl dont know why they cant create it?

Very few know that they can still create it someway.. but donno why are they supposed to do exactly like that..

Try out creating a folder named CON or LPT or COM1

Not only CON, we cannot create any of these
CON, PRN, AUX, CLOCK$, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, LPT9 and more

The reason is that con, prn, lpt1..lpt9, etc are underlying devices from the time dos was written. so if u r allowed to create such folders, there will be an ambiguity in where to write data when the data is supposed to go to the specified devices. In other words, if i want to print something, internally what windows does is -- it will write the data to the folder prn (virtually u can call it a folder, i mean prn, con, etc are virtual folders in device level). So if we are able to create con folder, windows will get confused where to write the data, to virtual con folder or real one.

So Now, Try this...

Open the Command prompt by Start -> Run and typing cmd

C:\> md \\.\c:\con
Now, Open My Computer and browse through the path where you created CON folder... Surprising.. ?? Yeah.. you have created it successfully

Now, try to delete the folder from My computer

OOPS!!! You cant delete it...

Now, try this in command prompt console

C:\> rd \\.\c:\con
Thank You.@dattu
