ok, thx i did it 
via
"Abusing" Rename Scripts to do other things with file info
@leo - could you please have a lock!
The script is working fine by my noob-standards 
but only if the artist name consists of one word 
[code]@script vbscript
Option Explicit
Function Rename_GetNewName(strFileName, strFilePath, fIsFolder, strOldName, ByRef strNewName)
Dim strInfoArray
Dim strCommand
Dim Shell
Set Shell = CreateObject("WScript.Shell")
' The strNewName is given the mp3artist tag info
strInfoArray = strNewName
DOpus.OutputString "The artist is " & strInfoArray
strCommand = "dopusrt /Cmd GO I:\metal\"& strInfoArray &" OPENINDEST"
Shell.Run strCommand,0,false
' Set strNewName to an empty string so that Opus does not rename the file.
strNewName = ""
End Function [/code]
