Windows 10 storage

Why does all C folders file size and Local Disk C proporties Used space does not match ? Difference is 38gb of unknown space. All junk files are removed by this method and recycle bin is empty!

Is it normal or not ? And what is your personal result....

This is normal. It is because some system folders and files (including restore points - which can be rather large) are not directly accessible by the user so are not counted. If there were HUGE differences (like 100s of GB), it might indicate some corruption, but I see nothing alarming in your screen shots.

As said above also things like pagefile.sys and hyberfil.sys will likely be using a large portion of that space you can't see, you can edit the explorer Windows view to see hidden files and operating system files if you're concerned or just curious to learn, just don't go deleting those kinds of hidden files if you don't know what they are or what they do.

just don't go deleting those kinds of hidden files if you don't know what they are or what they do.

Even if you tried, you can´t delete important system files, they are hidden for a reason.

After another restart i got even better results. These junk files takes a lot of space! I got down from 310GB to 262GB "Local Disk C proporties Used space" That's like size of one decent pc game.

Right now unknown space is only 19GB....

If you don't use hibernation or fast startup, open CMD as administrator and type

powercfg /h off
shutdown /r /t 0 (for a clean reboot)

Will free 32 GB from hibernation file. (your system specs claim you have 32 GB RAM)

I don't advise disabling the page file, but leave it on system managed - it'll save space and increase as needed. Capping system restore point storage to 1-2% of drive capacity can also help, but will reduce amount of available restoration points, and depending on how many things are installed in program files, you may need at least 10-15% of capacity there.

Because ever since the tail end of the XP/LH era WinSxS has been a thing. Component Based Servicing is a huge part of the Windows internal software stack.
My suggestion is to only mess with the parts you're sure about and that means using the basic install/uninstall routines provided by Windows.
Also a lot of things like hibernation files, update files, the system PAGEFILE and many others are marked as system components and (super)hidden by default.
You won't see any of them without Hidden items checked.

I can cut things down pretty good since I have a fair idea of what I'm doing but with each iteration of Windows it becomes significantly easier to break all of it.
Then there are rolling updates, tons of broken update packages and all the other junk that's engineered with the same diabolical file structure as SharePoint.
The longer these builds exist, the less worth messing with any of it but I need to exercise a bare minimum level of control just to make Windows behave.

I really need to do a lot of cleanup soon.

You can get yourself all ruffled up over nothing here. Unknown does not mean wasted or lost forever space. Windows is actually very good at managing resources - contrary to what some want us to believe. You have over 1.5TB of free disk space. Should you get down to critical levels, Windows will automatically free up what it absolutely does not need. But if you get that low, you have bigger issues to deal with - like buying more space, or uninstalling programs you don't use.

38gb out of 1.8tb.....
yes, normal
OCD, yes, normal (or not)

either someone needs help, or is just plain bored AF IMHO

Windows can't count multilayer folder trees (the more folders in folders it sees, the less accurate the count) - Try to use SpaceSniffer.
Windows SoftwareDistribution folder can also weight a lot and Windows system files can get dumb ("clean" drive with system files option should help with that).

Huh? Sure it can. Please show us a link to a reliable source that says otherwise.

This is not about Windows being about to tally up totals for file sizes in subfolders accurately - it can. This is about files and folders being visible for counting. It should also be noted this information is being gleaned from the file system.

If you are under character limit, sure.
However, shouldn't counter "just work" regardless of how you name folders ?
My point was : It WILL break if your folder path is over ~255 characters long (ie. it will not count whatever files are beyond that limit).
You can do whatever you want with files themselves (open/close/edit), they simply won't show up on search or... when moving them to different partition.
Got this issue when my mom wanted to do a backup of her pdf/epub book collection (with year/source/author/type/series/title + number in folder's name).
It was a pain...
