It seems a bit fragile to be parsing the output of `fsutil volume diskFree` as the output seems to vary by Windows releases and maybe configuration. So minimally, I think it should be changed to use ProcessTools so that the command and the output show up in the .jtr file.

In passing, you might want to choose a different method name to make it clearer what it does, maybe volumeDiskFree?
