reason for unable to create con folder

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
Creating:
C:\> md \\.\c:\con
Deleting:
C:\> rd \\.\c:\con
That's all
