Win32_VolumeQuotaSetting - powershell.one

The Win32_VolumeQuotaSetting association WMI class relates disk quota settings with a specific disk volume.

Methods

Win32_VolumeQuotaSetting has no methods.

Properties

Win32_VolumeQuotaSetting returns 2 properties:

'Element','Setting'

Unless explicitly marked as writeable, all properties are read-only. Read all properties for all instances:

Get-CimInstance -ClassName Win32_VolumeQuotaSetting -Property *

Most WMI classes return one or more instances.

When Get-CimInstance returns no result, then apparently no instances of class Win32_VolumeQuotaSetting exist. This is normal behavior.

Either the class is not implemented on your system (may be deprecated or due to missing drivers, i.e. CIM_VideoControllerResolution), or there are simply no physical representations of this class currently available (i.e. Win32_TapeDrive).

Element

KEY PROPERTY WIN32_LOGICALDISK

Reference to the instance representing the disk volume instance for the associated disk quota settings. This property overrides the Element property inherited from CIM_ElementSetting.

Get-CimInstance -ClassName Win32_VolumeQuotaSetting | Select-Object -Property Element, Setting

Setting

KEY PROPERTY WIN32_QUOTASETTINGS

Reference to the instance representing the quota settings instance associated with the referenced logical disk. This property overrides the Setting property inherited from CIM_ElementSetting.

Get-CimInstance -ClassName Win32_VolumeQuotaSetting | Select-Object -Property Element, Setting

Selecting Properties

To select only some properties, pipe the results to Select-Object -Property a,b,c with a comma-separated list of the properties you require. Wildcards are permitted.

Get-CimInstance always returns all properties but only retrieves the ones that you specify. All other properties are empty but still present. That’s why you need to pipe the results into Select-Object if you want to limit the visible properties, i.e. for reporting.

Selecting Properties

The code below lists all available properties. Remove the ones you do not need:

$properties = 'Element',
              'Setting'
Get-CimInstance -ClassName Win32_VolumeQuotaSetting | Select-Object -Property $properties

Limiting Network Bandwidth

If you work remotely, it makes sense to limit network bandwidth by filtering the properties on the server side, too:

Get-CimInstance -Class Win32_VolumeQuotaSetting -Property $property | 
Select-Object -Property $property

Selecting Instances

To select some instances, use Get-CimInstance and a WMI Query. The wildcard character in WMI Queries is % (and not “*”).

The parameter -Filter runs a simple query.

Listing all instances where the property Caption starts with “A”

Get-CimInstance -Class Win32_VolumeQuotaSetting -Filter 'Caption LIKE "a%"' 

Using a WQL Query

The parameter -Query uses a query similar to SQL and combines the parameters -Filter and -Property. This returns all instances where the property Caption starts with “A”, and returns the properties specified:

Get-CimInstance -Query "SELECT Element, Setting FROM Win32_VolumeQuotaSetting WHERE Caption LIKE 'a%'"

Any property you did not specify is still present but empty. You might need to use Select-Object to remove all unwanted properties:
Get-CimInstance -Query "SELECT Element, Setting FROM Win32_VolumeQuotaSetting WHERE Caption LIKE 'a%'" | Select-Object -Property Element, Setting

Accessing Remote Computers

To access remote systems, you need to have proper permissions. User the parameter -ComputerName to access one or more remote systems.

Authenticating as Current User

# one or more computer names or IP addresses:
$list = 'server1', 'server2'

# authenticate with your current identity:
$result = Get-CimInstance -ClassName Win32_VolumeQuotaSetting -ComputerName $list 
$result

Authenticating as Different User

Use a CIMSession object to authenticate with a new identity:

# one or more computer names or IP addresses:
$list = 'server1', 'server2'

# authenticate with a different identity:
$cred = Get-Credential -Message 'Authenticate to retrieve WMI information:'
$session = New-CimSession -ComputerName $list -Credential $cred

$result = Get-CimInstance Win32_VolumeQuotaSetting -CimSession $session

# remove the session after use (if you do not plan to re-use it later)
Remove-CimSession -CimSession $session

$result

Requirements

To use Win32_VolumeQuotaSetting, the following requirements apply:

PowerShell

Get-CimInstance was introduced with PowerShell Version 3.0, which in turn was introduced on clients with Windows 8 and on servers with Windows Server 2012.

If necessary, update Windows PowerShell to Windows PowerShell 5.1, or install PowerShell 7 side-by-side.

Operating System

Win32_VolumeQuotaSetting was introduced on clients with Windows XP and on servers with Windows Server 2003.

Namespace

Win32_VolumeQuotaSetting lives in the Namespace Root/CIMV2. This is the default namespace. There is no need to use the -Namespace parameter in Get-CimInstance.

Implementation

Win32_VolumeQuotaSetting is implemented in Wmipdskq.dll and defined in Wmipdskq.mof. Both files are located in the folder C:\Windows\system32\wbem:

explorer $env:windir\system32\wbem
notepad $env:windir\system32\wbem\Wmipdskq.mof
