We seem to have a number of NTFS drives like this where they consume much more space on the virtual disk than they do as files.
Noticed the problem when Windows Server Backup was taking-up much more space than the files themselves.
As am example, we have a small drive with mainly office documents:
- Size of actual files: 2.78Gb
- Disk properties used: 6.03Gb
- Size of compressed .vhdx: 27Gb
It is not the recycle bin, I have deleted that. It is not shadow copied, I have deleted them.
There doesn't seem to be any way of defraging these virtual drives on Server 2012 so nothing we can do there either.
Any other suggestions what is taking up this much space?
