Listing mount point disk free space using PowerShell

Working for a customer who had no monitoring solution in place, I had to write a PowerShell script to administer the free disk space on disks attached via mount points.

get-wmiobject win32_volume|
select Name, Label, 
@{Name="Capacity (GB)";Expression={$_.Capacity/1GB}},
@{Name="FreeSpace";Expression= {$_.FreeSpace /1GB}},
@{Name="FreeSpace (%)";Expression={[math]::Round(($_.FreeSpace/$_.Capacity*100),0)}} |
format-table

Executing the above PS script we get the below result.

Name                    Label                             Capacity (GB)               FreeSpace         FreeSpace (%)
----                    -----                             -------------               ---------         ---------------
