What I need to do is create an Action using the Wizard to password protect and restrict editing all PDFs in a folder.
I had one set up on my previous version of Adobe but now I have changed to Adobe Acrobat DC and I've lost my previous actions.
In the Actions Wizard I can't find an option to password protect, only to encrypt which still allows editing of the pdf.
I can do it on a single pdf but need to do a whole folder of pdfs.
