We have a tag named file, 30 questions, 1 follower, no tag wiki. I think the tag should be burninated (i.e. deleted), since it serves no purpose. It is both broad and vague at the same time. Aren't all questions somehow about files?
You can not be an expert in "files". If you asked someone "What's your area of expertise in information security?" and they answered "files" you would be quite surprised. Perhaps therefore the tag is used quite randomly.
I think we would be better of using these more specific tags instead:
If it should not be burninated, it should at least get some usage guidlines that explains when it should be used and when not. But since I don't understand how this tag could be used in a meaningful way I can't write those.
