For a typical user who belongs to the age of MS-DOS , the discussions on why you can not create a file or directory named CON on your machine does not make much sense. But for a new age user who directly exposed him or her to GUI , it may be a nice topic of discussion
There are so many discussions going on the social networking sites about why you can not create a folder named CON .
In Microsoft operating system environment , the word CON refers to console which is considered as standard input. The word PRN is representing the printer device attached to your parallel port , the word COM refers to communication port and so on .
So the operating systems will not permit you to create folders or files using these words because they are considered as device files
Take the case of a typical file creation process in your command prompt
type the command copy con newfile , a file named Newfile is created by standard input redirection . ie copying what ever you typed in to the console to a file named Newfile .
So your operating system assigns a special function to the file named CON .
since a folder is nothing but a file with a directory attribute , we can not create a directory named CON.
But if you are really keen to create a folder named con on your system , type the steps on the screenshot below
