怎样得到一个系统盘的全名，不是字符，是全名，如：本地磁盘(C:)？

Private Sub Command1_Click()
Dim ShellApp, oPanel, FolderItem1, FolderItem2, oItem
Set ShellApp = CreateObject("Shell.Application")
Set oPanel = ShellApp.NameSpace(0)
Set FolderItem2 = Nothing
For Each FolderItem1 In oPanel.Items
If FolderItem1.Name = "我的电脑" Then
Set FolderItem2 = FolderItem1.Getfolder: Exit For
End If
Debug.Print FolderItem1.Name
Next
If FolderItem2 Is Nothing Then
MsgBox "找不到项目！"
Exit Sub
End If
Set oItem = Nothing
For Each oItem In FolderItem2.Items
Debug.Print oItem.Name
Next
End Sub

输出结果如下：
控制面板
3.5 软盘 (A:)
WINDOWS98 (C:)
程序 (D:)
本地磁盘 (E:)
数据备份 (F:)
光盘 (G:)
