Challenge For you: Create and Delete Folder Named 'con'

It is not possible to create a folder named con. This is very interesting
fact. In MS-DOS, several special “device files” were available to aid
in performing certain tasks, such as clearing the screen or deleting
extraneous output from a program. In order to maintain
backwards-compatibility, all versions of Windows up to and including
Windows 7 will refuse to allow you to create a file with these “reserved”
device file names.

Con is a reserved name from the early days from DOS. It stands for
he “CONSOLE” I/O device
Like con , many other reserve words are there which we can’t create.
PRN - It stands for printer.
AUX - It stands for Auxiliary device.
NUL- It stands for bid bucket.
COM0, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8,
COM9 - stands for serial ports.
LPT1,LPT2,LPT3,LPT4,LPT5,LPT6,LPT7,LPT8,LPT9- stands for parallel ports.
Here i discuss about creating con folder and it can be achieved by
cmd. Atfirst run cmd.

Then you decide in which your hard-disk drive
you want to create nul folder. Suppose you want to create in D-drive.
Now in cmd type md\\.\d:\con and hit Enter,check in your D drive,
nul folder is created.
Now once the folder is created , it cannot be deleted by the keys
of mouse or keyboard. To delete it,in cmd type rd\\.\d:\con and
hit Enter , nul folder will be deleted.
Like nul you can create and delete other system folders mentioned
above in the same method , just replace nul with name of system folder
you want to create while typing in cmd.

Thats it !!!!!!!!!!!!!!!
