Okay.
So here’s the next issue: We like our file names :P.
Also, I have never had much luck with the second option. I’ve always gotten long and lengthy error messages with lots of coding language (which I am, regrettably, not fluent in). If the PDF file does replace, then I’m still stuck with the old file name links on the front end.
Maybe from now on I’ll use the second option, but I’ll make sure any new files have the exact same file name. I guess I’ll see what happens?
