Now that the question has been answered I just want to correct the misconception that the file type concept as embodied in the “filename.ext” format was just “aping DEC VMS”. VAX/VMS was an outgrowth of the PDP-11 series, and its operating systems, like the RSX-11 family, RSTS/E, and others, all used filename extensions in just the same way. So did the OS for the PDP-10 before that, which itself was the successor to the PDP-6, and that goes back to 1963. So did OS/8 for the PDP-8.
So in fact the “filename.ext” format was pretty much deeply ingrained throughout the entire DEC product line, going back to the first disk-based operating systems. It was far more fundamental and ubiquitous than your comment would have us believe. And that product line included among the most innovative and brilliantly engineered operating systems ever produced, by anyone, bar none. To suggest that the only “sane” operating systems are those with a Unix background is, I presume, intended as tongue-in-cheek and far from the truth.
You know, I lived that*, but I don’t have the mistaken belief that anyone else would care.
And yes, I did like DEC systems and OSs. I happen to like Unix more, for perfectly cromulent non-partisan and rational reasons.
*TOPS-10 on PDP-11 ca. 1979

Regarding caring: One should care about it as a significant part of computer history, and history, as they say, is important because it tells us how we got to where we are.
Regarding “TOPS-10 on PDP-11 ca. 1979”: Was that a typo? Otherwise if you lived it, you didn’t live it hard enough.

Yup, that’s sorta a typo. More like a thinko, since I conflated it with the PDP-11 I briefly worked with later in life.
The system I was originally thinking of did banner itself as a DECSYSTEM 10.
Of course, this is all pretty off-topic, unless you contend that Pinterest is hosting their web services off of DEC minincomputers.:dubious:
TOPS-10 was the OS for the PDP-10 (DECsystem 10). The PDP-11 ran RSX-11M, D, and S, RT-11, and RSTS/E.
