不用FSO的复制文件夹得方法？
用API函数 SHFileOperation
以下是使用SHFileOperation删除复制移动文件的例子，可以复制文件夹
Private Type SHFILEOPSTRUCT
　　hwnd As Long
　　wFunc As Long
　　pfrom As String
　　pTo As String
　　fFlags As Integer
　　fAnyOperationsAborted As Long
　　hNameMappings As Long
　　lpszProgressTitle As String '只有在 FOF_SIMPLEPROGRESS 时用
End Type
Private Declare Function SHFileOperation Lib _
"shell32.dll" Alias "SHFileOperationA" (lpFileOp _
As SHFILEOPSTRUCT) As Long
'wFunc 常数
'FO_COPY　 把 pfrom 文件拷贝到 pTo。
Const FO_COPY = &H2
'FO_DELETE 删除 pfrom 中的文件（pTo 忽略）。
Const FO_DELETE = &H3
'FO_MOVE　 把 pfrom 文件移动到 pTo。
Const FO_MOVE = &H1
'fFlag 常数
'FOF_ALLOWUNDO 允许 Undo 。
Const FOF_ALLOWUNDO = &H40
'FOF_NOCONFIRMATION 不显示系统确认对话框。
Const FOF_NOCONFIRMATION = &H10
'FOF_NOCONFIRMMKDIR 不提示是否新建目录。
Const FOF_NOCONFIRMMKDIR = &H200
'FOF_SILENT 不显示进度对话框
Const FOF_SILENT = &H4
'例子：
Dim SHFileOp As SHFILEOPSTRUCT
' 删除
SHFileOp.wFunc = FO_DELETE
SHFileOp.pfrom = "c:\config.old" + Chr(0)
SHFileOp.fFlags = FOF_ALLOWUNDO + FOF_NOCONFIRMATION
Call SHFileOperation(SHFileOp)
' 删除多个文件
SHFileOp.wFunc = FO_DELETE
SHFileOp.pfrom = "c:\config.old" +Chr(0) + "c:\autoexec.old"+Chr(0)
SHFileOp.fFlags = FOF_ALLOWUNDO
Call SHFileOperation(SHFileOp)
' 拷贝
SHFileOp.wFunc = FO_COPY
SHFileOp.pfrom = "c:\t"
SHFileOp.pTo = "d:\"
SHFileOp.fFlags = FOF_ALLOWUNDO + FOF_NOCONFIRMMKDIR
Call SHFileOperation(SHFileOp)
' 移动
SHFileOp.wFunc = FO_MOVE
SHFileOp.pfrom = "c:\config.old" + Chr(0)
SHFileOp.pTo = "d:\t"
SHFileOp.fFlags = FOF_ALLOWUNDO + FOF_NOCONFIRMATION
Call SHFileOperation(SHFileOp)
或者
shell "cmd.exe /c xcopy "+chr(34)+"C:\新建文件夹 c:\aa /q /e" +chr(34)
