A Reason Behind the Con Folder Creation in Windows

We all know that we can't create Con, Folder in windows. not only con but also " PRN, AUX, CLOCK$, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, LPT9 and more".

Here i am going to explain why you can not create the con folder in windows.

Reason:

We can not create folder with con,aux, nul because these are reserved keywords used by DOS. 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.

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
