Why We Can't Create Con Folder in Windows ?

A Reason Behind Why We Can't Create Specific Folders in Windows

Most of us are aware, we can't create a folder with name "Con" in windows and all most many of us don't know the reason.

Well I present you the reason and list of keywords which we can't use in windows to create folders or file.

Reason:

We cannot create folder with con, aux, nul because these are reserved keywords used by DOS. So if we were allowed to create such folders than there will be an ambiguity, in where to write data when the data is supposed to; go to the specified devices.

 

Keywords and Their corresponding Functions:

Reserved Keywords	Function
CON	Keyboard and Display
PRN	System list device, usually a parellel port
AUX	Auxiliary Device,usually a serial port
NUL	Bit-Bucket Device
A:-Z:	Drive Letter
COM1	First Serial communications port
COM2	Second Serial communications port
COM3	Third Serial communications port
COM4	Fourth Serial communications port
LPT1	First Parallel printer port
LPT2	second Parallel printer port
LPT3	Third Parallel printer port
