How do I view the size of a mount point drive on 2008R2?

The size column tells me the capacity of the drive but not the amount of disk used.

How do I determine how much data is on a mount point in 2008 R2? Any GUI or powershell command is fine.

get-wmiobject Win32_volume |select Name,Capacity,Freespace

That'll get you a list of everything, including mount-points, and their capacities.

As for GUI, it's there just a bit hidden. When you go to properties on the mount point itself, there is a button on the first page that'll give you the disk-stats same as you would at the root of something like C:.

You could also take a look at this powershell script:

It has proven to be very handy when monitoring lots of mountpoints.
