I want to know how to automatically find the Windows installation directory under the DOS prompt. For example, in a batch file, I need to automatically add a file to the system directory. But the system directory is not necessarily C:\WINDOWS\ or C:\WINNT\. How to do this?

It seems there is an environment variable called WINDIR, and the value of this variable is the installation directory of WINDOWS. I can't remember clearly. Please help think about it.

Yes, you can use %WINRAR% to find the Windows installation directory. If you want to copy a file to this directory, you can use: copy XXXX.XXX %WINDIR% and note that WINDIR must be in uppercase.

Then can I use a %systemroot%?
It's like this. del %systemroot%\temp\*.* /q /f |

Is there an environment variable called systemroot? In DOS, you can use the SET command to find all environment variables.

Below is the quote from Gu Huo Long on 2004-2-9 9:07:26:
Can I use a %systemroot% then? This is the case. del%systemroot%\temp\*.*/q/f Then it's better to use %temp% Below is the quote from mys on 2004-2-9 11:41:33: Is there the systemroot environment variable? You can use the SET command under DOS to find out all environment variables. It exists in NT based systems |

That %SYSTEMROOT% cannot be found in the variables, but it can be used.
SORRY. I mean it can be used in the command prompt of XP, WIN2003. Maybe it's a system - reserved one. |
