Get drive path of operating system

[Sn3akyP3t3]

I cannot find a means to identify the path of the OS drive without a degree of sloppiness and in all environments.

So far the only two means I know of are like so:

1.) Works so long as the home path resides on the same drive the OS does. Useless to me in my work environment.

$dir = @HomeDrive
MsgBox(0,"",$dir)

2.) Works for the most part, but really sloppy. Becomes a pain when having to use the path literally in comparisons or when treated as a string for StringCompare() functions since it needs to be sanitized of the workaround addition in the path before use.

$dir = @WindowsDir & '\..'
FileChangeDir($dir)
$dir = @WorkingDir
MsgBox(0,"",$dir)

Of course FileChangeDir() doesn't need to be used. It just produces quick viewable results to describe my problem.

What if you grab the first three chars with StringLeft?

$sWindowsDir = StringLeft(@WindowsDir, 3)
MsgBox(0, "", $sWindowsDir)

Gives the same result as your script in half the lines

Thanks! Leave it to me to over-analyze the simple stuff!

EnvGet() is also handy to know if you want to use values from environmental variables.

$systemdrive = EnvGet('SystemDrive')
MsgBox(0, '$systemdrive', $systemdrive)

Edit:

fixed typo
