Hard drive is showing more used space than reported

So, I've got this hard drive divided into four different partitions. Most of them seem to be behaving just fine, but there's one particular partition that's giving me some trouble. Just to be clear, it isn't my C: drive or anything like that.

So, I’m looking at my drive, and things seem a bit... off, I guess. According to the system, I have 54.4 GB free out of a total 292 GB. But then, when I actually open up that partition and highlight everything to check the properties, it tells me the size on disk is 163 GB. It feels like the math just isn't adding up, or maybe I'm missing something obvious here.

So, I was doing some math earlier—292 minus 163 should equal 129. Based on that, I'm expecting to see about 129 GB of free space available, but instead, it’s only showing 54.4 GB. It feels like there's roughly 74.6 GB of free space just... missing? I guess I might be overlooking something, but the numbers definitely aren't adding up for me right now.

Does anyone have any idea what might be going on here? I'm feeling a bit stuck.

So, I've got "show hidden files" turned on, but I'm still scratching my head. How can I actually figure out what exactly is eating up 74.6 GB of space, and what's the best way to go about clearing it out?

Have you checked the settings for the space reserved by the Recycle Bin yet? Just right-click it and hit Properties.

Is this what I'm looking at:

Yeah, I went ahead and capped my C: drive (the system partition) at 1GB, and for all the other drives, I just turned off the shadow copies entirely. Now I have to be super careful about what I delete, because once something hits the trash, there’s really no way to get it back.
If you want to test how this works, try setting a 100GB limit on all your partitions first. That should give you a clear idea of how much actual free space you'll have left on them.

I get what you're saying. But I've been looking at my D drive, and everything seems totally fine there—total space, used space, free space, it all adds up correctly. It’s just that 74.6 GB on the F drive feels like such a massive, weird discrepancy.

I have this nagging feeling that the reason is something really simple... maybe something right under my nose that I'm just completely overlooking.

I'm going through my installed programs now. For instance, I wondered if some download manager might have "reserved" a huge chunk of space, but I don't think that's the case so far.

P.S. I definitely wouldn't want to mess around with resizing partitions myself; I'm really no expert at that kind of thing.

Look, this isn't some kind of "messing around." They basically leave it up to the user to decide how much space to set aside, and I just took advantage of the option to reserve nothing at all—so when I hit "delete," those files are gone for good.
After reading what you wrote, I’ve gotta wonder... have you ever even used the Empty Recycle Bin before? 🤔

Of course I'm emptying the Recycle Bin. When I mentioned "messing around," I was actually referring to resizing partitions (assuming I caught your drift there). The thing is, just clearing out the trash doesn't quite solve my whole problem.

Am I reading this correctly? ...

If you convert those KB into GB, it looks like there should be about 127 GB available, which is pretty much exactly what I was expecting to see, rather than whatever number is actually showing up on my screen.

You can't—not easily. It’s a massive headache. Which version of Windows are you running? Have you even bothered trying to run Disk Cleanup yet?

Right-click the partition -> Properties -> Disk Cleanup

Running that process on a 300GB drive may take a while..

Windows 10. I haven't actually clicked anything yet, but when I ran Disk Cleanup on my F: drive, it just shows 0 bytes.

So, I went ahead and toggled the setting to show hidden files. Now all I'm seeing is $RECYCLE.BIN and System Volume Information. Both of them are basically sitting at zero bytes. I've seen some people online suggesting that I should just delete the $RECYCLE.BIN folder and then reboot, but I'm honestly not sure if that's a good idea or if it would even make a difference. No matter how I slice it, I'm still missing about 75GB compared to what my hard drive says is available when I just click on the drive icon. It’s kind of weird, though, because after running chkdsk, it claims there's more free space available—basically exactly what I was expecting to see in the first place.

Look, we all know that Windows 10 is prone to its own particular brand of mental instability—I’m convinced the OS is capable of reporting a half-full battery as being at 150%—so if I were in your shoes, I simply wouldn't waste my breath worrying about this specific issue right now.

Once you start loading more files onto the drive, Windows will likely correct its math and provide a more accurate count, and besides, from what I can see, your hard drive isn't exactly small anyway.

Look, what I suggested isn't going to mess with your hard drive partitions at all. Your partitions stay the exact same size and all your data stays right where it belongs. It’s just that the settings tell Windows how much space to RESERVE specifically for system junk. Because of that, the OS blocks you from using that chunk of space for your own stuff, which is why it looks like you've got less free room. Once you shrink that reserved space, you'll see that extra capacity again.
