Adding border to multiple documents

[dk1204]

Hi all, I have well over 2000 files that I need to add a custom border to. I am wondering if there is a more efficient way to go about this than going into each file one by one.



Is it possible to add a border multiple files at once?

If it's at all helpful, I have these thousands of documents exported to pdf. So if there was a solution to add borders to multiple pdfs at once, that would be an option too.

Thanks in advance,
Scott
