    Morning all!

    This is an odd one. I had this many years ago, and never got it resolved, but let's try again.

    Why have I got 100GB of missing space?

    As you can see... Windows reports 165Gb and WinDirStat reports 49Gb. With what's installed.... I'd expect around 50GB.

    WinDirStat is seeing the pagefile, so it's not that. Hibernate is off... and even so... 100GB? Although WinDirStat appears to report no user files, that's because they're not on C: Even taking this into account, make no sense, as "My Documents" is MASSIVE... it's clearly reporting that correct as 0... there are no user files that I know of on C:

    Help!

    Are you running WinDirStat with administrative privileges?

    Does selecting all the files and displaying the properties tally with those you get when just displaying the properties of the drive?

    I am, yes.

    No... opening C: and selecting all visible files and folders shows roughly the same figure as WinDirStat... around 49Gb

    System Restore images? IIRC they show up as 'used' space, but don;t show in windirstat

    might want to run

    Code:
    vssadmin delete shadows /all
    just to be sure, iirc turning it off doesn't always remove old restore points.

    Use SpaceMonger 1.4 instead. Basic, old program, but always worked flawlessly for me.

    It's probably a permissions thing, WinDirStat and selecting all files > properties is most likely not listing a file or files you don't have permissions for whereas drive > properties does.

    You could try using AccessEnum from sysinternals and see if that turns up any VHD's or other large files that have been left over from when a program was uninstalled.

    Try TreeSize free edition and run as administrator. I use at work all the time and always bang on.

    Yep.. that did it!

    For some reason, this folder "CSC" has copies of stuff on my server in there.


    Thanks for the help everyone.

    run cleanmgr, that little lot should [iirc] show up as 'Oflline Files'

    CSC stands for 'Client-side Cache' and... well... you can probably guess what it is/what it's for.


    There is a way to turn it off... but can't remember how at this exact moment.

    I know what it was. When I did this new install of Win10, the Sync App started running on my network drives... those files were just what it had synced as "offline" before I disabled sync.

    Mystery solved. :)
