HI MYSELF DIPANSHU SRIVASTAV
I READ ON GOOGLE THAT MICROSOFT CORP. IS UNABLE TO CREAT FOLDERS NAMED CON , LPT1, PRN, COM1...FOLDER WITHOUT NAME...BUT I CAN DO IT... I ALSO READ THAT IT IS IMPOSSIBLE TO MAKE FOLDER CON.....................BUT I WILL DO IT IT IS POSSIBLE.......We can create a folder with CON name. Create a folder and right click and select Rename option. Then just press Alt and without releasing Alt button press 255 from the keyboard and then type con. That’s it. You will see a folder named CON.
Reason why you cannot rename it normally is it that CON is one among many system reserved names.

Re: CON folder is possible

There are ways described in internet regarding this !!!

And BTW who wants to create that ??

What are the uses of creating that file in system??

Can you state what differences can we make creating a folder named CON?

I guess its of no use creating that folder in windows.

Any use please share!!

The BEST-EST BEST WAY OF CREATING FOLDER NAMED CON

RUN>CMD> type the command with the drive letter you want: mkdir \\.\e:\con
and to remove: rmdir \\.\e:\con

but as u know that nothing is perfect in this world...so it has its own limitation.....just explore and find out....

PLEASE COMMENT and also add me to your friend list...pleaseeeeeeeeeeeee

Hi guys, I search on google and found these points at one of the site.

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.

Now to make con folder-

Open the Command prompt by Start -> Run and typing 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 cant delete it...

Now, try this in command prompt console

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

Explanation of this:

Well, let us now have a glance at how we were able to create it...

It is just because of the UNC Path (#-Link-Snipped-#. The Universal Naming Convention, or UNC, specifies a common syntax to describe the location of a network resource, such as a shared file, directory, or printer.Since, these conventions did n't exist under pure DOS, they are not backward compatible. The UNC syntax for Windows systems is as follows..

\\RemoteHost\sharedfolder\resource

where RemoteHost is the computer name / IP address of the computer that you wish to connect through remotely for accessing shared folder. The rest is the path.

(Here \\remotehost\drive:\con doesn't make sense anyway, because without having a process on the remote host, there is no current 'console'). It would be a security hazard as well, having the serial and parallel ports accessible for everyone who is allowed to read or write in any single directory.

The "." in the command \\.\c:\con suggest the local server. Now, you are pointing to your own computer. since, you have all privilages on every folder of ur computer, you can easily create it.

NOW I hope it is clear to everyone that what is real mystery behind this.😎

if you press alt+255 (or alt + 160 for some comp.systems) you get a blank character, after that you type 'CON' which consists of 3 characters.

' CON'

So there are total four characters (i.e 1.) Blank Character 2.) Letter 'C' 3.) Letter 'O' 2.) Letter 'N')

Now these four characters you have created does not match with the original three!

' CON' is not equal to 'CON' (notice the blank character in first keyword)

So this is how you can create CON folder.
