It's not a bug - it's a feature: reserved filenames which have special features and functions. And it has been preserved through DOS, and Windows over the years as part of Microsoft's philosophy of "compatibility at all costs".

There are many, many examples of similar (mis)features. Not sure why this particular one is getting so much attention. But yeah, if you know the history, it's not really surprising.

For anyone interested in this sort of software archeology, have a look at Raymond Chen's blog https://blogs.msdn.microsoft.com/oldnewthing/ which is full of this stuff. Very interesting reading.

"The file AUX.H is too large for the system"

That's a bug. It should say something closer to "The filename AUX.H is a reserved filename and can not be used by this system"

I just tried it on Windows 10, and the error message is:

    This file name is reserved for use by Windows. Choose another name and try again.

So at least that has been fixed.

Never used it. What’s this screenshot from?

That's Win10. I suspect in that screenshot that the file is indeed too big for the filesystem. I don't know how that could be (the "no more free space" message is different.)

9.57KBytes? That would be a very full disk!

Or a very oddly formatted one.

The disk full message is different, so my money is on an oddly formatted disk.
