  grep -RHn "_content_" .

I just did it more tongue-in-cheek like the unneeded cat commands.

There’s definitely use cases. If you want to search for a keyword on the file name, that one’s great.

Perhaps it’s because I lived in the days before search was even a thing.

Lots of options, plenty of opportunity for confusion.

A special kind of insanity that puts me in a mild, cold sweat. Such filesystems can come for your family too!

Worth noting, my father was an early adopter of the home computer. It's somehow regressed over the years.

And then complains to you all their files have disappeared.

Usually it's because they've run out of diskspace and windows has created a temporary profile for them (which is crazy default behaviour when you think about it). Not sure if that's still a thing.

Of course they just closed the popup saying "you're running low on diskspace" last week. After all, what are they supposed to do about that?

The more documents you have, the more likely you are to have strict classifications. The stricter the classifications the more likely you are to run into something like Russell's paradox.
