I have 1000's of PDF that all need to have their headers added and modified to show the following:
"Filename" / "Page Number"
Thus far I have managed to use the Action Wizard in Acrobat DC to get all the headers in the PDF's to show:
xx (Placeholder text) / 1 (using the page number function in headers & footers)
How does you add the headers?
I used the Action Wizard and the Add Header & Footer tool.
You need to use a script. For example, you can add a unique (read-only) text field to each page and then apply that text as its value. There's no built-in option of doing that with the Add Header & Footer tool.
For the filename use form text fields or watermarks.
