Getting System32 folder location with java

Question

On XP and above, my System32 folder is at C:\WINDOWS\system32. On Windows 2000 it is at C:\WINNT\system32. Is there a

System.getProperty("something");

or some way that I can get the location of the System32 folder?

Answer 1

Since I think NT, the way to get it through environment variables is: %WINDIR%\system32

You can do this:

String sysdir = System.getenv("WINDIR") + "\\system32";

More default environment variables for windows on Wikipedia: http://en.wikipedia.org/wiki/Environment_variable#Examples_from_Microsoft_Windows

SYSTEMROOT and WINDIR are identical in NT systems, but WINDIR also works for older, 9x kernel-based windows.

This should work:

String system32Path = System.getenv("SystemRoot") + "\\system32";

On my installation of Windows XP, typing set SystemRoot in a Command Prompt returns C:\Windows

Answer 3

The environment variable SYSTEMROOT will give you the location of the windows install point (something like 'C:\Windows'). Construction of the full path to the System32 directory is of course, simple ('C:\Windows\System32').
