Now I am less confused I think. You never actually coded any save file code. I believe you are looking at the PDF software. Is is something like?
You are going to have to code your own save as (I think). Do you want to move it or just make a copy?
I have never done this, but my first guess would be
1. I already know the file location since the user picks it.
2. If you know the path (which you do), you can use the file system object to move or copy the file.
3. Code a file save dialog and use FSO to move or copy.
Maybe someone who has done this has a better idea, but that should work.
