powershell - How to get disk capacity and free space of remote computer

Question

I have this one-liner:

get-WmiObject win32_logicaldisk -Computername remotecomputer

and the output is this:

DeviceID     : A:
DriveType    : 2
ProviderName :
FreeSpace    :
Size         :
VolumeName   :

DeviceID     : C:
DriveType    : 3
ProviderName :
FreeSpace    : 20116508672
Size         : 42842714112
VolumeName   :

DeviceID     : D:
DriveType    : 5
ProviderName :
FreeSpace    :
Size         :
VolumeName   :

How do I get Freespace and Size of DeviceID C:? I need to extract just these two values with no other informations. I have tried it with Select cmdlet, but with no effect.

Edit: I need to extract the numerical values only and store them in variables.

Answer 1

$disk = Get-WmiObject Win32_LogicalDisk -ComputerName remotecomputer -Filter "DeviceID='C:'" |
Select-Object Size,FreeSpace

$disk.Size
$disk.FreeSpace

To extract the values only and assign them to a variable:

$disk = Get-WmiObject Win32_LogicalDisk -ComputerName remotecomputer -Filter "DeviceID='C:'" |
Foreach-Object {$_.Size,$_.FreeSpace}
