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. The following file names are reserved:
CON, incidentally, was a device file used to capture whatever was printed onscreen.
let me tell you a small secret you can’t even create a folder named PRN, AUX, NUL and many others like..

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.
