I have a large number of .pdf files located in the same folder. I need to be able to quickly view page 1 of each file in succession without having to open and close each one individually. I need the same functionality that I have with images using Irfanview..the ability to open one file and then move forward or backward using key commands. Does this function exist in the full version of Acrobat or in any other free or paid alternative? So far I’ve been unable to find a solution. Thanks for any assistance.
