    I noticed as well.

    Is it confirmed that there should be a very high degree of agreement regarding reported sizes among these different programs?

    I wouldn't expect identical sizes, but I don't use more than one such prog so wouldn't notice how much discrepancy is typical.

    Did you recently do the Feature update, to Win 10 v2004?
    If so, there should be a windows.old file located on the root of the C: drive.

    Despite the size disparity, none of those sizes are 19.4GB apart.

    Twice Windows Update tried to give me the v2004 Feature Update (which failed twice), but during the process it had created two $xxxxxxx files on C:. I was wondering if that may be the mystery file(s).
    Since the Feature Update failed, it emptied those $xxxxxxxx files, but if it succeeds, I'm wondering...

    Check to see if there is a windows.old file. This can be found at C:\. If it is there, how big is it?

    Do you have a disk search tool other than built-in Windows? Something like Everything, that can search the Master File Table and sort by size.

    I suspect it wouldn't be found even then because it's just bad reporting or unexplained space, so would not have an MFT entry.

    Yes Everything is a good choice => Download Everything 1.4.1.969

    I hope this helps!

    I would run chkdsk c: /f, from an admin command prompt and allowing a restart check and see if that shows or changes anything.

    Did you contact the developers of that app and ask if they've seen this before?
