Virtual Machine - C: Volume has been allocated 70GB, 60GB used, can only account for 33GB? see insid

Hi all,

OK we have a Windows server hosted on our ESXi host, its a terminal server.

It has a C Volume which has been allocated 70GB from our datastore, there is no other volume existing on this machine as we dont need it.

Now they had a problem with space recently, so had to increase the C volume slightly.

I am trying to find out what folders are using this space.

If you look at the properties of the C volume, it says exactly 60GB is being used, however, if you go in to the C volume, un-hide all the folders and files, select all and click properties (this includes all Windows folders, system folders etc etc) it only accounts for 25GB, I cant see any other directories on this C volume.

I have also found another 8GB being reserved by the Windows pagefile.

Thats a total of 33GB, my question is where is the other 28GB being used? I have done a disk clean-up to check for any compressed old files being, there is nothing to clean up.

google treesize and run it on the server it will tell everything.

Or try windirstat.

Ta, will give these a go to see if it can find where its being used.

WinSXS would be my guess

Shadow copies of the c drive?

Restore point(s) and/or hybernation files going under the radar?

Run Windows Explorer as Administrator as you may not have permission to enumerate all folders which would give you a scewed space report? If applicable to the OS you are running of course.

Install treesize and run as administrator. Should tell you where the big files are.
