Get free disk space for mount points using Powershell

Question: How can I get the capacity & freespace on Windows drives including mount points using Powershell. 

Answer: Win32_Volume class “represents an area of storage on a hard disk”.     Normally - we may look first at Win32_LogicalDisk class  “represents a data source that resolves to an actual local storage device on a computer system running Windows”.    

A volume mount point is a drive or volume in Windows that is mounted to a folder that uses the NTFS file system. A mounted drive is assigned a drive path instead of a drive letter. By using volume mount points, you can  mount, a target partition onto a folder on another physical disk.

--Get freespace and capacity of every drive & mountpoint on a Windows servers. This will return the figures as bytes

--Add the -computername switch if you need to check remotely 

Get-WmiObject Win32_Volume  -computername MYCOMPUTER| Select-Object driveletter,Label,@{Name='freespace';Expression={[math]::Round($_.freespace/1GB,2)}},@{Name='capacity';Expression={[math]::Round($_.capacity/1GB,2)}}
