Copy pdf file to new pdf file

I'm using Oracle report 6.0 to create a pdf file for my delivery notes with following command...
rwrun60.exe vkp_ldsk.rdf userid=xx PA_VRL_NR=400296 DESTYPE=PRINTER DESFORMAT=PDF DESNAME=PDFCreator
BATCH=YES
Where PDFCreator is my printer on Windows system. BATCH=YES means that all will done in the background. PA_VRL_NR is the paramter that is sended to the report to collect all information for this delivery note.

After the print is done the file is in the given directory which is in my profile. I can add all parameters but not the delivery note number...
I think I have to copy the pdf to another directory with another filename...
The file after the print is called LL- but should be LL-00400296.PDF...
How can I automatically copy and rename the pdf-file in PDFCreator ?
Please help me out...I read some things about scripts...but I am such a nerd in those things...
Greetings,
