取出根路径

1 $text = "\127.0.0.1D$HotfixHotfix_Win20032014-04"
2 $pathRoot = [System.IO.Path]::GetPathRoot($text)
3 $driverLetter = $pathRoot[-2]
4 Join-Path ("$driverLetter" + ":") $text.Substring($pathRoot.Length, $text.Length - $pathRoot.Length)

$pathRoot的返回值为：\127.0.0.1D$

判断路径：

test-path "filesystem::\127.0.0.1d$"
