Why folders with the name CON can’t be created in Windows??

Some people don’t know why they can’t create it?
Very few know that they can still create it someway. But don’t know why are they supposed to do exactly like that.
Now, After reading this ,you will become one of the rest.

Not only CON, we cannot create any of these

CON, PRN, AUX, 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 ugydevices. 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 type cmd

Code:
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 can’t delete it…

Now, try this in command prompt console

Code:
C:\> rd \\.\c:\con

Yeah!! You did it…
