My Hard Drive filled up overnight out of nowhere

So, here’s the situation: just a couple of days ago, my C Drive had about two-thirds of its space sitting there completely empty. But somehow, overnight, the bar turned bright red, and now it’s telling me that out of 244 GB, I’ve only got 13 GB left. I’m honestly baffled. Over the last few days, the only thing I’ve actually done is download three little movie conversion programs, and those shouldn't be taking up nearly this much room.

To make matters worse, when I tried to open Photoshop—which is basically where I spend my entire life working—it wouldn't even let me start a new document. It just gave me that dreaded "scratch disks are full" error message. Now, I'm effectively paralyzed; I can't get anything meaningful done on my computer at all. It’s a total standstill.

I’ve already gone through the motions of cleaning things up—deleting most of my movies, emptying the Recycle Bin, getting rid of some massive .psd files from old projects, and clearing out a few downloads and random programs I don't need anymore. But despite all that effort, the available space hasn't budged even a tiny bit.

Does anyone have any advice on what I should do next?

When I tried to open Photoshop—which I use every single day and basically depends on my livelihood—it wouldn't even let me start a new document because it kept throwing a "scratch disks are full" error. My computer is essentially useless right now; I'm completely blocked.

I've already nuked most of my movies, cleared everything out of the Recycle Bin, deleted several massive .psd files, and tossed out some old downloads and unused software, but the available space hasn't budged a single millimeter.

What should I do?

Just download this tool https://windirstat.net/ and you'll see exactly what's eating up your drive.

or just fire up Disk Cleanup

Try running a disk cleanup or CCleaner—and honestly, you should probably check how much space those system restore points are hogging up...

Since you mentioned downloading those movie conversion tools, there's a chance one of them might have saved a file in a really massive format by mistake, I guess.

I suppose that could be it, though the original movie on my E: drive is only about 1.68 GB, and I only have a single backup copy sitting on my F: drive.
To make matters worse, none of those conversion programs actually worked anyway; it turns out they were designed specifically for Mac, so I never even managed to convert the film into ProRes.
I went poking around through my Apps and ended up deleting all three Data Recovery programs, which freed up a decent amount of space on my C Drive, though I suspect there's still some hidden mischief lurking somewhere. I downloaded that utility mentioned earlier (WinDirStat), and it pointed me toward the MSoCache folder. It's always tucked away and invisible, so you can't find it in the standard settings menu. From what I've read online, it's either nearly impossible to delete, or if you actually manage to pull it off (which I couldn't quite do, despite following the instructions since I couldn't locate the specific directory), it just crawls back in every time Windows runs an update or something along those lines.

Hi everyone—my laptop finally gave up the ghost after five years of solid service, and the only thing I managed to salvage from the wreckage was the Hard Drive. Now I'm wondering if there is any way to make that drive function like a standard USB stick? Is there a specific cable or adapter out there for this purpose? If so, what exactly should I be looking for, and what kind of price range am I looking at?
Also, is it necessary to get some kind of protective case to keep the Hard Drive safe from dust and debris?

If you're looking to get that hard drive up and running, an external drive bay is probably your best bet, and honestly, there are plenty of budget-friendly options out there. You just need to make sure the dimensions actually match your specific drive so you aren't left with a useless piece of plastic.
Of course, if you happen to be working with a desktop tower, you could always just mount it directly inside the chassis if you’re feeling particularly adventurous; all it really takes is plugging in a SATA cable and a power lead, provided you have the extra ports available.
