Can i rename a folder as con in windows operating system. if not why?

--------------

No, because in programming terms, 'con', is short for console, which means your screen. It is used to send output to 'con' or the console. It's an internal command in DOS and the word 'con' cannot be used by anything else... if you absolutely insist that you have a folder named con, name it C-o-n, C_o_N or c0n, <--C zero n that's the only way i know of to do it

-----------------
It's not that weird. 'con' is a reserved word from the old DOS days, simply meaning 'console'. If you wanted to create a new text file in DOS you could type 'copy con newfile.txt' meaning copy from the console to newfile.txt. This would let you type some lines and when you ended the file with ^Z (DOSish for 'end of file') you would have a file called newfile.txt containing whatever you wrote in the console. This is indeed still possible in the Windows XP console, and can you see what mess it would cause if you let files or folders have the name 'con'? What would 'copy con newfile.txt' then mean?

Also the following list of other DOS devices cannot be used as folder 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.

But yes u can still rename it and delete and i have done it lot of time, well u can also do it.

mkdir \\.\d:\con
mkdir con\
mkdir \\?\d:\con

all these work.... with any device name, con, lpt1...lpt9, prn etc


and yes check the source i have given down u will find many tips and tricks in windows forum.
