Dear Bernd,
thanks for the hint. I tried to do that but without success. Maybe I do not understand it completely. I did the following:
1) copy the word documents and subfolders to the Destination. Then I ran the Action. (Destination was a different Folder, not the source)
2) same as 1), but source and Destination Folder was the same.
In both cases I have ALL the pdf-documents directly in the top Destination Folder.
Do you have an idea where my mistake could be?
Kind regards,
Mathieu
