The total space contained by the windows (C) files and folders is 54 GB whereas the used space as shown in windows (C) properties is 81 GB.

That's normal.
Windows File explorer has never been capable of calculating the size of C:\Windows so any total that includes C:\Windows will be incorrect.
You'd need a third-party utility such as Treesize [free] to get a better answer.

I noticed that you had Hidden folders-files displayed but not System folders-files but that would not change the unavoidable inaccuracy of the calculation.
On mine, there is a 15GB difference between used space & total size on disk calculated by your addition if only Hidden folders-files are shown. If I also set System folders-files to be displayed, the total is only 5GB out.
I'm surprised by the scale of your system's inaccuracy. But I'd always use TreeSize anyway.

Well C:\windows is just 1 folder on the root of your drive. You have other folders too like C:\Program Files and C:\users and C:\ProgramData and all of these folders are going to consume space that will be part of that used 81GB.

For me both explorer and Treesize show the exact same numbers for used space on C:
You misunderstand me.
- The used / unused space figures are not inaccurate.
- The total size of folders-files arrived at by adding those of individual folders, as the OP has done, is inaccurate [because it includes C:\Windows].

All the best,
Denis

I added a bit to my post #4 to reduce ambiguity [but I see that the OP has marked the thread solved already].

All the best,
Denis
