GetEffectivePermission

The GetEffectivePermission method in CIM_DataFile is implemented by WMI.

This documentation is derived from the CIM class descriptions published by the DMTF. Microsoft may have made changes to correct minor errors, conform to Microsoft SDK documentation standards, or provide more information.

Example

Do not run below example code just to see what happens next. Many methods seriously affect your system. Always make sure you actually understand what the method and the code do.

param
(
  [Parameter(Mandatory)]
  [UInt32]
  $Permissions
)


$query = 'Select * From CIM_DataFile where Name='c:\\windows\\explorer.exe''

Invoke-CimMethod -Query $query -MethodName GetEffectivePermission -Arguments $PSBoundParameters

To run this method on one or more remote systems, use New-CimSession:

param
(
  [Parameter(Mandatory)]
  [UInt32]
  $Permissions,

  [String[]]
  $ComputerName,

  [PSCredential]
  $Credential
)


$session = New-CimSession -ComputerName $ComputerName -Credential $Credential

$query = 'Select * From CIM_DataFile where Name='c:\\windows\\explorer.exe''

Invoke-CimMethod -Query $query -MethodName GetEffectivePermission -Arguments $PSBoundParameters -CimSession $session

Remove-CimSession -CimSession $session

Syntax

boolean GetEffectivePermission(
  [in] uint32 Permissions
);

Parameters

Permissions

List of permissions that the caller can inquire about. You can combine bit flags.

Requirements

To use CIM_DataFile, 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

CIM_DataFile was introduced on clients with Windows Vista and on servers with Windows Server 2008.

Namespace

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

Implementation

CIM_DataFile is implemented in CIMWin32.dll and defined in CIMWin32.mof. Both files are located in the folder C:\Windows\system32\wbem:

explorer $env:windir\system32\wbem
notepad $env:windir\system32\wbem\CIMWin32.mof
