    Windows Folder Size greater than Size on Disk

    My 32GB Windows 10 Home PC (recently upgraded from 8.1) is low on disk space. I deleted Windows.old and I have hibernation disabled. Apart from a few browsers, very little else is installed, yet I only have 11.7GB left?

    One reason may be the size of the Windows folder:
    Size 14.7GB
    Size on Disk 9.91GB

    From my calculations, Windows appears to be using the higher figure in determining available disk space.

    Why is 'Size' so much greater than 'Size on Disk', can I do anything about it? I have a similar 8.1 machine, it does not have this disparity (12.4GB and 12.3GB).

    What would be a normal 'Size' for a Windows folder on Windows 10 Home PC very recently upgraded from 8.1 i.e. with few, if any Windows live updates run ?

    I imagine its because windows compresses some system files currently it may be using 9gb but with all files uncompressed you may be looking at 14 which is why it uses the higher value

    Actually Windows isn't using either 14.7 GB or 9.91 GB numbers. Both of those are at best only an approximation. The only number Windows cares about is that reported in the volume properties which will always be exact. Numbers based on usage of individual folders take time to produce and can never be anything other than an approximation in any modern file system.
