Invalid name "Con"

I tried Con as name of a folder, but the system will not accept it. Does anybody know the reason?

Solution

  • This is reserved and specified in IO.SYS and date back from the early MS Dos days. Here is a brief list:

    CLOCK$ - System clock

    CON - Console; a combination of keyboard and screen to handle input and output

    AUX or COM1 - First serial communicationport

    COMn - Second, Third, ... communicationport

    LPT1 or PRN - First parallel port

    NUL - Dummy port, or the "null device" which we all know under Linux as /dev/null.
