    So at work we mainly have a virtual set up. We have 4 physical servers but as we use vmware esxi we have 20 virtual servers. All are managed by the network admin and we also have outside help if needed. There is a problem with the staff server were the staff upload and save stuff. This drive will rise from say 150 gig to 200 or 175 to 230 gig for no reason that we can think of. The numbers are just for an idea etc , however the staff have not been complaining of any file losses so I can think of only 2 things. A random back up or a virus maybe ? I say virus because of the fact they come in various shapes and sizes. And because of the permissions then maybe it's populating a drive and deleting itself as it causes damage. I am just grasping at straws here and also passing time while Im waiting for the doctor, nothing serious tho

    Grab WinDirStat or a similar disk space analyzer and get digging - you'll soon find the culprit folder locations and can move on from there.

    I had an nVidia driver cause 40GB of my SSD to be chewed due to Windows generating a few hundred thousand registry recovery points due to a false "driver update" event - not likely it's this but you get the idea.

    I would also be looking at the VMware stats for the VM's and seeing if you can narrow down the times that this is occurring.

    I can't think of any VMware related issue that would cause the drive to expand and contract as much as it is, are these dedicated data drives (ie a D: or E: drive) or just large extended C: drives (I have seen it happen).

    Also worth asking, are these servers also running other services apart from running as a file server (for example a SQL server instance running with nightly maintenance plans being run that could cause disk usage to grow)?

    Have you looked at the Windows event logs to see if anything is showing up there?
