vb怎样在文件夹中搜索指定名称的文件，并用msgbox将文件位置输出？我新手请将代码解释下。

Public Sub ShowFolderList(folderspec)
On Error Resume Next
     Dim fs, f, f1, s, sf
     Dim hs, h, h1, hf
     Set fs = CreateObject("Scripting.FileSystemObject")
     Set f = fs.GetFolder(folderspec)
     Set sf = f.SubFolders
     For Each f1 In sf
    
     If Dir(folderspec & "\" & f1.Name & "\" & Text2, vbDirectory) <> "" Then
     MsgBox folderspec & "\" & f1.Name & "\" & Text2
     Exit For
     End If
       If folderspec & "\" & Text2 <> "" Then Call ShowFolderList(folderspec & "\" & f1.Name)
     Next
End Sub

Private Sub Command1_Click()
If Right(Text1, 1) = "\" Then Text1 = Left(Text1, Len(Text1) - 1)
ShowFolderList (Text1)
End Sub
