“An Indian discovered that nobody can’t create a FOLDER anywhere named as “con“. This is something pretty cool….and unbelievable . At Microsoft the whole Team, including Bill Gates, couldn’t answer why this happened!!!”
In Microsoft’s Windows operating systems like Windows XP or in Vista we cant create folders with names CON, PRN, AUX, CLOCK$, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9 directly from GUI. This is because, DOS device names are reserved words, and cannot be used as folder or file names.
Okay do one thing press Alt and type 255 from NUM keys and then tried to write any one of name from given list : CON, PRN, AUX, CLOCK$, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9 ; and see it happened .
or still confused okay best trick is
2. press md\\.\\c:\<dir path>\con
< dir path > is path for making this folder
3. press Enter to make it.
in DOS shell 'copy con' is a command for making a file.
like: "copy con new.txt"
and 'copy' is for copying a folder
so, it is reserved command by its creators to avoid ambiguity.
