weird punnet square of results:

EDIT hangs if you open "CON", but errors if you try "C:\CON\CON"
Win95 errors if you try to open "CON", but crashes if you try "C:\CON\CON"

@foone

Wasn't there also once a bug in Win7 or 8 that caused it to hang in kernelspace and bluescreen with these once?

@foone No, I mean something way more recent. Cause that together with early days Minecrafrt modding (where you had to unzip the jar file and then at some version there was a file named "AUX" in it)

where when I learned about these special filenames for the first time. And I didn't play minecraft on anything less recent than win7, so...

@agowa338 oh that's not a bug, that's an intentional design decision. windows reserves a bunch of filenames and it's a pain

the bug where this crashed the machine hasn't been there since windows 95, that's a separate issue

@foone

No there was a similar crash bug in Win7. Then they must have reintroduced it at some point.

And the AUX one the bug was then with minecraft as it would silently drop that file when unzipping and then the unzipped jar wouldn't properly execute anymore.

I just wanted to add that piece to nail down the timeframe of when I a similar bug.
