I would prefer that we do not use these terms like BS and nonsense. That is not a civilized discussion.

This is a tough situation.

On the one hand, you yell at the op:

A common misperception is that a file "exists within a directory". No!

But this is exactly how it works, despite the actual implementation details.

A file exists within a folder, that is why they are called files and folders, this is the model .

So yes, if you're going to yell at someone and correct someone for using the same model everyone is taught, yes, this is bullshit.
