Nobody can create a FOLDER anywhere on the computer which can be named as “CON”. This is something pretty cool…and unbelievable. .. At Microsoft the whole Team, including Bill Gates, couldn’t answer why this happened?

Anon:
This is really simple:
CON is a reserved word in DOS which is the device Console (screen)
Also, PRN (printer) is a reserved word.
This was used in DOS command line days to redirect the output to the printer or screen.
I.e. "copy filename.ext > con" will display the contents of the file on the screen.
"copy filename.ext > prn" will print the contents of the file on the printer.
