都不完好，我想楼主的意思是创建无极深度文件夹吧，给个我写的： 

'创建新目录(同意无级创建)
Public Function CreateFolder(FolderPath)
Dim sObjFSO
Dim arrFolder
Dim i


Set sObjFSO = Server.CreateObject("Scripting.FileSystemObject")
FolderPath = Replace(FolderPath,"\","/")
arrFolder = Split(FolderPath,"/")
On Error Resume Next


For i = 0 To UBound(arrFolder)
If i > 0 Then arrFolder(i) = arrFolder(i-1) & "/" & arrFolder(i)
If Not sObjFSO.FolderExists(arrFolder(i)) Then
sObjFSO.CreateFolder(arrFolder(i))
End If
Next
CreateFolder = True


If Err.number <> 0 Then
CreateFolder = False
Err.Clear
End If
End Function

创建目录

dim fso,SavePath
SavePath=server.MapPath(".\"&imagefile&"\"&username&"\"&specialname&"")
set fso = server.CreateObject("scripting.filesystemobject") 
if fso.FolderExists(SavePath)=false then 
fso.createfolder(SavePath) 
end if
set fso=nothing

删除目录

dim fso,SavePath
SavePath=server.MapPath(".\"&imagefile&"\"&username&"\"&specialname&"")
set fso = server.CreateObject("scripting.filesystemobject") 
if fso.FolderExists(SavePath)=true then 
fso.deletefolder(SavePath) 
end if
set fso=nothing

拷贝文件

dim fso
set fso=server.CreateObject("scripting.filesystemobject")


sub copyfiles(path,path2)
  set mycopy=fso.getfile(path)
  response.flush()
  mycopy.copy path2
  response.write("<b>installed success !  </b>"&path2&"<br>")
  response.Flush()
end sub
call copyfiles(Server.MapPath("../无标题2.bmp"),"D:\站点项目\photo\aspupload\07_images\")
