Explorer does two things. Read the entries and sort them. Looks like reading is linear and sorting too. So you get N^2 time behavior. This didn’t change for decades.
Some file systems allow accessing the files with a kind of pointer, avoiding the directory once you know the pointer. Nevertheless, adding and deleting files still has to touch the directory.
Looking up directory names has the same problem. So better construct a directory “tree”.
File size doesn’t matter for name lookups.

A while ago I dropped half a mug of coffee over my cheap USB keyboard and of course it died. Been given a Corsair K68 RGB, a mechanical keyboard (+ non spill mug). Sturdy keys, good for bulk typing. So, few days ago, the unthinkable happened - I dropped a full mug of coffee on the new keyboard.
..and it still works, without flaws. There's an anti-spill rubber between the keys and the internals, and there's a metal covering under that which protects the electronics. I'm convinced that nothing is idiot proof and I will find a weak spot, but for now, I'm pretty impressed. It's easily taken apart and cleaned and might actually last longer than a year.

Really boring - a MS 600 I bought after my Logitech died. And I only got the Logi because after 20 years of abuse the keytop legends had nearly all worn off and Herself complained that she didn't know where the letters were ...

What a wastrel! Don't you know that you can get the keyboard re-engraved?

That would have cost more than the keyboard did!
It was a cheap one I bought my first "fast" computer (to play Doom2 properly): A DX4/100 with ... gasp ... 16MB of RAM.
For the yoof, that's not a misprint: 16 megabytes of RAM, and 100 megahertz processor (running an internal clock tripler from the 33MHz bus speed).
It was blindly fast, for it's time.
The keyboard survived many upgrades that nothing else from the original did ...

Did your case have the jumpers so you could set the "speed" you wanted - especially to annoy the gullible when you set your Turbo switch (remember those as well!) to show 128 instead of 66 ...

I honestly don't recall the jumpers. This was my very first PC and I wanted whatever the Computer Shopper said was cool. The Pentium had already peaked when these new "overclockers" were starting to come out. I knew nothing but that I was future-proofing by investing in the "next big thing". But I do remember the prominent turbo push button and wondering why you would ever not want it on - it wasn't as if running it at a blistering 66 made the lights dim.

Something from digital (DEC) probably made in the 90s. 101 keys, as the Maker intended.

Is the control key in the right place? I have to remap my keyboard to get the control key next to the 'A' key. I"m an old fart and still use WordStar control sequences for text editing.

Sadly, it's a pretty standard IBM-style 101-key keyboard. It can be difficult to use with DEC software, such as no proper "Gold" key, etc.

I use to have a programmable mechanical keyboard (can't remember brand) that I got in the early 80's just to be able to reprogram the control key. It eventually died but I was able to write a TSR to remap the Control key. Eventually with Windows I found a keyboard mapper utility (Ziff-Davis) that lets me do the remap. The remap utility still works under Windows 10.

Also mechanic, cheaper - but not anti spill

I have a Razer Blackwidow too, but I'm not all that impressed. Oh, it's very pretty, but I've only had it a year or two and some of the key mechanisms have already become flaky. I'm currently suffering through an update to Synapse that ate my simple configuration file and makes it harder to create a new one. One other thing, I can type so fast on the Razer that I make mistakes that I don't make on other keyboards. I'm not sure it's a net-positive.

C'mon, that's hardly the keyboard's fault.

It isn't exactly the keyboard's fault, but if good typists make more mistakes on this keyboard than on a slower keyboard, is it the best tool?
I'm just reporting my experience. You can make of it what you will.

I use a code keyboard, I don't know which cherry color are the keys..
It is sturdy, good touch.
I'd rather be phishing!

Cheap Logy USB wireless for coding and gaming. I’m a lousy typist and mediocre gamer, so I don’t deserve better.

I recently replaced a cheap Logitech keyboard with a Logitech Craft - certainly not among the cheaper ones.
My experience with it is limited to a couple weeks. There is no doubt that I am now typing significantly faster. My subjective impression is that I am making fewer typing mistakes as well.
One positive thing I did not expect: Even though the keys have a significant stroke length, my typing is almost perfecty quiet! (My ex would have loved it - she was frequently complaining about the terrible noise from my keyboard! - but that is long ago.)
It takes a little while to get accustomed to a new keyboard. For me: The top button in the rows above the arrow keys is no longer insert / home / PageUp - they are in the second row. The top row switches between up to three different computers that the keyboard may be connected to, wirelessly. I certainly appreciate and make use of that option, but it takes a little while to adjust your fingers to hit the right key when there is a new row of them!
Bottom line: The replacement is great, and ceratinly worth the money for the upgrade.

MS Wireless 850.
It does the job, and in 40+ years I have never (touch plastic ) spilt things on my keyboard.

MS800 at home; MS850 at work (I brought it in from home, four years ago, then they all went wireless but I kept my old one). There are many blank keys on it, so my programming is very hit-and-miss (I tried to teach myself touch typing but was very unsuccessful). Fortunately, as I am still forced to be working from home, I am using my home keyboard which still has letters on it.

I'm behind the desk, say, 4-6 times a day with coffee and a smoke or two. Statistically, I got more change to spill stuff. Add to that a morning routine with coffee and a smoke, where one isn't quite awake.
Lots clumsy. But the keyboard, it was prepared for that
