Hi. I have a software program that creates custom files, let's say BBB. I have a Word 2016 add-in which opens these BBB files in Word. I have 1,500 of these files and am looking for the best way to save these files as PDF.

I've tried opening Word and selecting the files, which opens them for viewing in Word but in Compatibility mode. To save from there, it seems like I have to save one at a time. Is there a way to open/convert to Word/save in one fell swoop?

From there, I could convert to PDF.

Thank you for any and all advice!
