>I would like to rename a folder. The command 'RENAME' doesn't work. I would also like to prevent the use of an AktiveX. Any idea how to do it?

There's two easy ways. First, there's the API

FUNCTION RenDir
  * AUTHOR: George Tasker
  * DATE: July 2, 1998 - 1:38 PM
  * PURPOSE: Renames a directory

  LPARAMETERS tcoldname, tcnewname

  DECLARE INTEGER MoveFile IN Win32API;
     STRING @lpcurrentname, STRING @lpnewname
  LOCAL lcoldname, lcnewname, llresult
  lcoldname = tcoldname
  lcnewname = Tcnewname
  llresult = (MoveFile(@lcoldname, @lcnewname) # 0)
  RETURN llresult
ENDFUNC

Second, as Hilmar mentioned there's the Windows Script Host

oFSO = CREATEOBJECT("Scripting.FileSystemObject")
* lcpath is the fully qualified file name
oFolder = oFSO.GetFolder(lcpath)
* lcnewname is the name of the new folder
oFolder.Name = lcnewname
