When you download and save a LOT of information, it’s important to know what the information is about at quick glance. Obviously, the people who name some of their PDF or ZIP files have no clue.
I have to assume that the reason(s) they don’t name their files to achieve this is goal is because…
- They aren’t sure how to name the file when generating a PDF or creating the ZIP; and/or
- They aren’t paying attention and just accept the default given.
