Renaming PDF files with RO

I am being paid to rename 3,563 PDF files using an RO number located in the top right corner. Just as the original author of this post has stated, the number varies in its location from time to time but is however always in the top right corner. My files are indeed PDFs and are supposed to be saved as PDFs as well, just renamed. Based on searches I see that I will be using AUTOMATER but unfortunately I am completely new to this application and have no idea where even to begin. Is there anybody here who could maybe help me? It would rescue me from having to perform 9 hours of work I'd imagine.

I have attached a screen shot example of one of the PDF's, the number in the top right corner circled in blue is what I will be using to rename each of the files. If this helps at all, the folders contain documents 6560634-6564197. (3,563 unnamed documents). I was told to click on each .PDF > copy text > and rename said document with pasted text. Individually, one can imagine how arduous a process these kind of jobs can be. I would be so grateful to anybody who can offer a valid solution.

cheers,

Gene
