"Hey Linux, can you just delete this file please?"
"Sure thing bud, a program is using it, it's ok, I will just unlink the inode anyway, the program can still access it until it closes the file"

This is honestly one of my favorite features of the linux filesystem. As a dev it makes things like replacing and hot-reloading plugins way easier.
It turns out you can kind of get the same functionality on Windows if you rename the open file and place the new one with the original name, but it's a bit of a hack.
Windows won't let you rename a file that's being used either.
Yeah, super annoying. In Linux you can rename or move it and the app using it doesn't care.
Although having the option of listing the app using a file so I can kill the app would also be really nice to have. I'm sure Linux has something for that too, but I don't know what it is.

In case anyone is interested, there's a powertoy called file locksmith that will show what's using it and let you kill it: https://learn.microsoft.com/en-us/windows/powertoys/file-locksmith
"Time to see who's stopping me from deleting this file... svchost??? Goddamn it!"
just kill it
Instructions unclear, I shot my gaming rig with a 6 bore shotgunβ¦. And then set it on fire.

Probably the indexing service, it's always the indexing service.

Powertoys seems to be the only thing keeping windows somewhat usable, I have no idea why they don't include it in the build.
I discovered powertoys only recently, and it's a pretty cool set of tools. From color picker, tiling window manager to regex file renames or copy/paste tools, it has a lot of QoL features.
If you have to be on windows, i.e due ro work, I recommend not sleeping on it.

Me: I've close the program, now please delete the file
Windows: ok, give me half an hour, it's not easy to delete 500 MB
... And the file is back open somehow. Only now the program throws an error when Windows launches, yet still leeches resources.
Here's an incredibly animated chart of how poorly I'm doing. Note that I seem to throttle the operation every 5 seconds or so.
Explanation? No, no. Haha. No. We don't do anything like that.

TBF the task manager and those windows explorer dialogues were programed in like 1996 and it's probably one of the best functioning feature in Windows so changing it too much carries high risks.
changing it too much carries high risks
This is such a Windows way of thinking. Why does every other OS constantly change and evolve but Windows is like βcanβt touch this code from a quarter century ago?β
Becuase it's still integral to countless businesses operations.
I don't see the problem with it. Microsoft historically does a great job of making everything worse with updates.

Lol yea, but it would have been such a small tweak with big big QoL improvements LMAO
You can use process explorer, it even has option to act as a replacement for task manager.

back in the XP days, I used a software called "Unlocker" just for this problem. It probably still exists, I don't know, because since Windows 7, the easiest way to find out what process locks a file is to open Resource Monitor (Start search: resmon) and on the CPU tab, using the "Associated handles" list, you can search for the file name and see the process in question (and kill it).
So yeah, Resource Monitor is a useful tool on Windows.
There's a collection of free little utilities called Microsoft PowerToys, including the file unlocker thing. Why would they not include these into base kit Windows is beyond me.
not including PowerToys inside basic package is a fucking choice. Win11 is literally unusable without it in many aspects.

Some of them felt a bit buggy when I last time used Windows, maybe they aren't fully ready to ship (like Samsung's Good Lock apps?). And most features didn't do quite what I imagined it to do, but that's probably a "me problem".

What gets me is when I'm not allowed to remove an external drive. Deleting a file can be delayed until later but here I am with a physical object that I need to detach from my computer and first I need to play hide and seek with the OS.
If this happens often, you can disable write caching for that drive. It'll feel slightly slower (since it's actually operating at the speed of the hardware instead of caching operations in RAM and gradually writing them to disk in the background), but you'll be able to remove the drive almost instantly.
I used to find it had something to do with the explorer thumbnailer finishing up but sort of not letting go. It would happen if I had pictures or videos on the USB drive, and if I got the error I could go to another folder like my documents, drag a picture into another folder, go look at the pretty new thumbnail, then I could remove the USB drive because the thumbnailer was 'parked' back on the C drive. Sounds like I'm making it up but I swear it worked.

And that removable objectβs filesystem is probably the most shit, unjournalled filesystem in the world so youβre actually fucked if it becomes corrupted by removing it early.

Some Windows apps do handle it properly. For example, if you have an archive open in 7-zip and try to delete it, Windows Explorer should correctly tell you that it's open in 7-Zip. I'm not sure why it doesn't work that way for all apps.
Windows doesn't even tell you if Explorer itself has a folder open... how the hell does 7-Zip do it?

Meanwhile on Linux: /boot successfully deleted
I once deleted /dev/null Do not recommend. Youβd be surprised how much of the system needs it.
I once deleted /dev/urandom. I didn't want uncertainty in my life.
Well, I was on for a surprise.

Actually on windows 7 I found out how to get which process is locking one file.
You open the resources manager (task manager has a link to it)
Inside you can see how much each process uses on cpu, network and stuff.
And there is a tab where all used files for each process is listed. You can search for specific files.
Yeah there's a Microsoft sysinternals utility where you can drag a file into to fetch that info for you.
Makes zero sense there isn't a >Details in the error notification that tells you the damned process in Windows.

Linux fuser for the win
I've never fused Linux before, is it difficult?
fuser is an easy command just point it at the file and it tells you the process ids that using that file.

It's one of the things that made me prefer using Linux a long long time ago. It's nice to be able to rename, move, and delete files while they are used.
Well duh, Microsoft respects privacy
Same thing whenever I try to unplug a USB, Win10, on my desktop. There have been times where I plugged in one, opened a file, closed it within seconds, did the safely remove thing, and then I get the whole quick song and dance about some program still using it because of how sluggish it is to actually end what's using it in the background.
Also, my phone's keyboard software was bugging out and replaced "song" with "incest" for no discernable and wanted to replace the next word "and" with "rape incest". Not related, but fuck Gboard and that weird glitch where it'll replace words with random shit for no reason.
Doesn't gboard try to promote words you've used more prior more often than ones you've used less...?
