Can You Make Folder Named 'CON' ?

Nobody can create a FOLDER anywhere on the computer which can be named as “CON”. 

This is something pretty cool…and unbelievable… At Microsoft the whole Team couldn't answer why this happened!


"Why we can't create a folder with name 'CON' " ?, and I’m sure most of us also try to make folder "CON" just now after reading the title of article ! if no, then go and 1st try it . If you try creating a folder named CON,  it’ll get renamed automatically to New Folder. But there is no mystery behind this, and the team at Microsoft very well knows the reason for this. :-)

Why is it not possible to create a folder named CON ? Before we proceed further, let me tell you a small secret you can’t even create a folder named CON, NUL, PRN and AUX and many others. The reason you can’t create a folder with these names is because these are reserved keywords used by DOS. The below screen-shot showing a list of reserved keywords in DOS.

If you try creating a folder with any of these names, the name automatically changes back to the default “New Folder”. And this is what has caused the confusion. Instead of automatically renaming the folder, had an explanatory warning message popped up.

You can actually create a folder named CON !!
There is actually a way to create a folder named CON, or any other name from the above

list of reserved keywords. This can be done through command prompt. But it is advisable not to do so, as it might result in your system becoming unstable.

Step 1: To create a folder named CON, go to command prompt and type “MD \\.\F:\CON” (without quotes). This will create a folder named CON in F:. See the screenshot.

Step 2: You cannot delete this folder by normal delete. To delete the folder, again go to command prompt and type “RD \\.\F:\CON” without quotes.

Step 3: we again recommend you not to try this on your system, as it might become unstable. In case you can’t stop yourself, don’t do it on a drive on which Windows is installed (default C:).
