2- Under Choose Tools to add > Click Protection > Encrypt > and click on + sign to add this to the right-hand panel (uncheck the box next to Prompt user).
3- Then click Save & Export > Save> and add it to right-hand panel (you can change output options by clicking on specifiy settings)
4- Click Save and give action a name. (for ex: Batch password).
5 - Go to Action Wizard > Actions > Batch password
6- Click on Add Files> select all the files you want to add password to and click Start.
And it does not work !
