That's fair, but do realize that sometimes people do have to send around archives from the last century (they got archived for a reason!) or created by eldritch-horror tools that just make weird files (which, sometimes, are the gold masters for certain very important outputs...). And it's kind of annoying when these weird but standard files get silently dropped. Especially when that same file went through just fine yesterday, before the duly zealous security settings changed for whatever reason.

All I'm saying is, don't drop my stuff silently because your code couldn't be arsed to deal with (ugly) standard formats. At least give me a warning ("file of type not scannable" or whatever, the actual words are not so important). And then when I have to yell at the Shanghai people I can yell at them for the correct reasons.
