核心代码

CreateFolders "d:\jb51test\1\2\3\4\5" 

Function CreateFolders(path)
	Set fso = CreateObject("scripting.filesystemobject")
	CreateFolderEx fso,path
	set fso = Nothing
End Function

Function CreateFolderEx(fso,path)
	If fso.FolderExists(path) Then 
		Exit Function
	End If
	If Not fso.FolderExists(fso.GetParentFolderName(path)) Then
		CreateFolderEx fso,fso.GetParentFolderName(path)
	End If
	fso.CreateFolder(path)
End Function

经过测试运行没问题

文中的两个函数链接CreateFolder 方法与GetParentFolderName 方法。
