The Win32_DirectorySpecification class represents the directory layout for the product. Each instance of the class represents a directory in both the source image and the destination image. Directory resolution is performed as follows:

Methods

Win32_DirectorySpecification has no methods.

Properties

Win32_DirectorySpecification returns 13 properties:

'Caption','CheckID','CheckMode','DefaultDir','Description','Directory','DirectoryPath',
'DirectoryType','Name','SoftwareElementID','SoftwareElementState','TargetOperatingSystem','Version'

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

Get-CimInstance -ClassName Win32_DirectorySpecification -Property *

Most WMI classes return one or more instances.

When Get-CimInstance returns no result, then apparently no instances of class Win32_DirectorySpecification 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).

Caption

STRING

Short description of the object.

Get-CimInstance -ClassName Win32_DirectorySpecification | Select-Object -Property CheckID, Caption

CheckID

KEY PROPERTY STRING

Identifier used in conjunction with other keys to uniquely identify the check.

Get-CimInstance -ClassName Win32_DirectorySpecification | Select-Object -Property CheckID

CheckMode

BOOLEAN

Condition is expected to exist or not exist in the environment. When TRUE, the condition is expected to exist (a file is expected to be on a system) so the Invoke() method is expected to return TRUE.

Get-CimInstance -ClassName Win32_DirectorySpecification | Select-Object -Property CheckID, CheckMode

DefaultDir

STRING

Get-CimInstance -ClassName Win32_DirectorySpecification | Select-Object -Property CheckID, DefaultDir

Description

STRING

Description of the objects.

Get-CimInstance -ClassName Win32_DirectorySpecification | Select-Object -Property CheckID, Description

Directory

STRING

Get-CimInstance -ClassName Win32_DirectorySpecification | Select-Object -Property CheckID, Directory

DirectoryPath

STRING

Name of a directory. The value supplied by an application provider is actually a default or recommended path name and can be changed for a particular environment.

Get-CimInstance -ClassName Win32_DirectorySpecification | Select-Object -Property CheckID, DirectoryPath

DirectoryType

UINT16

Type of directory being described.

DirectoryType returns a numeric value. To translate it into a meaningful text, use any of the following approaches:

Use a PowerShell Hashtable 
$DirectoryType_map = @{
Product log directory = '1'
Shared base directory = '2'
Shared executable directory = '3'
Shared library directory = '4'
Shared include directory = '5'
System base directory = '6'
System executable directory = '7'
System library directory = '8'
System configuration directory = '9'
System include directory = '10'
System log directory = '11'
  Other = '12'
}
Use a switch statement 
switch([int]$value)
{
  Product log directory {'1'}
  Shared base directory {'2'}
  Shared executable directory {'3'}
  Shared library directory {'4'}
  Shared include directory {'5'}
  System base directory {'6'}
  System executable directory {'7'}
  System library directory {'8'}
  System configuration directory {'9'}
  System include directory {'10'}
  System log directory {'11'}
  Other      {'12'}
  default    {"$value"}
}
Use Enum structure 
Enum EnumDirectoryType
{
  _1    = Product log directory
  _2    = Shared base directory
  _3    = Shared executable directory
  _4    = Shared library directory
  _5    = Shared include directory
  _6    = System base directory
  _7    = System executable directory
  _8    = System library directory
  _9    = System configuration directory
  _10   = System include directory
  _11   = System log directory
  _12   = Other
}

Examples

Use $DirectoryType_map in a calculated property for Select-Object 
<# 
  this example uses a hashtable to translate raw numeric values for 
  property "DirectoryType" to friendly text

  Note: to use other properties than "DirectoryType", look up the appropriate 
  translation hashtable for the property you would like to use instead.

System executable directory = '7'
System library directory = '8'
System configuration directory = '9'
System include directory = '10'
System log directory = '11'
  Other = '12'
}

#endregion define hashtable

#region define calculated property (to be used with Select-Object)

<#
  a calculated property is defined by a hashtable with keys "Name" and "Expression"
  "Name" defines the name of the property (in this example, it is "DirectoryType", but you can rename it to anything else)
  "Expression" defines a scriptblock that calculates the content of this property
  in this example, the scriptblock uses the hashtable defined earlier to translate each numeric
  value to its friendly text counterpart:

$DirectoryType = @{
  Name = 'DirectoryType'
  Expression = {
    # property is an array, so process all values
    $value = $_.DirectoryType
    $DirectoryType_map[[int]$value]
  }  
}
#endregion define calculated property

# retrieve the instances, and output the properties "Caption" and "DirectoryType". The latter
# is defined by the hashtable in $DirectoryType: 
Get-CimInstance -Class Win32_DirectorySpecification | Select-Object -Property Caption, $DirectoryType

# ...or dump content of property DirectoryType:
$friendlyValues = Get-CimInstance -Class Win32_DirectorySpecification |

    Select-Object -ExpandProperty DirectoryType

# output values
$friendlyValues

# output values as comma separated list
$friendlyValues -join ', '

# output values as bullet list
$friendlyValues | ForEach-Object { "- $_" }
Use $DirectoryType_map to directly translate raw values from an instance 
<# 
  this example uses a hashtable to manually translate raw numeric values 
  for property "Win32_DirectorySpecification" to friendly text. This approach is ideal when
  there is just one instance to work with.

  Note: to use other properties than "Win32_DirectorySpecification", look up the appropriate 
  translation hashtable for the property you would like to use instead.

<# 
  this example uses a switch clause to translate raw numeric

<#
  a calculated property is defined by a hashtable with keys "Name" and "Expression"
  "Name" defines the name of the property (in this example, it is "TargetOperatingSystem", but you can rename it to anything else)
  "Expression" defines a scriptblock that calculates the content of this property
  in this example, the scriptblock uses the hashtable defined earlier to translate each numeric
  value to its friendly text counterpart:

$TargetOperatingSystem = @{
  Name = 'TargetOperatingSystem'

    # property is an array, so process all values
    $value = $_.TargetOperatingSystem
    $TargetOperatingSystem_map[[int]$value]

# retrieve the instances, and output the properties "Caption" and "TargetOperatingSystem". The latter
# is defined by the hashtable in $TargetOperatingSystem: 
Get-CimInstance -Class Win32_DirectorySpecification | Select-Object -Property Caption, $TargetOperatingSystem

# ...or dump content of property TargetOperatingSystem:
$friendlyValues = Get-CimInstance -Class Win32_DirectorySpecification | 
    Select-Object -Property $TargetOperatingSystem |
    Select-Object -ExpandProperty TargetOperatingSystem

# output values
$friendlyValues

# output values as comma separated list
$friendlyValues -join ', '

Use $TargetOperatingSystem_map to directly translate raw values from an instance 
<# 
  this example uses a hashtable to manually translate raw numeric values 
  for property "Win32_DirectorySpecification" to friendly text. This approach is ideal when
  there is just one instance to work with.

  Note: to use other properties than "Win32_DirectorySpecification", look up the appropriate 
  translation hashtable for the property you would like to use instead.

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 = 'Caption',
              'CheckID',
              'CheckMode',
              'DefaultDir',
              'Description',
              'Directory',
              'DirectoryPath',
              'DirectoryType',
              'Name',
              'SoftwareElementID',
              'SoftwareElementState',
              'TargetOperatingSystem',
              'Version'
Get-CimInstance -ClassName Win32_DirectorySpecification | 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_DirectorySpecification -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_DirectorySpecification -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 CheckID, DefaultDir, Directory, SoftwareElementState FROM Win32_DirectorySpecification 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 CheckID, DefaultDir, Directory, SoftwareElementState FROM Win32_DirectorySpecification WHERE Caption LIKE 'a%'" | Select-Object -Property CheckID, DefaultDir, Directory, SoftwareElementState

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_DirectorySpecification -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_DirectorySpecification -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_DirectorySpecification, 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_DirectorySpecification was introduced on clients with Windows XP and on servers with Windows Server 2003.

Namespace

Win32_DirectorySpecification 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_DirectorySpecification is implemented in Msiprov.dll and defined in Msi.mof. Both files are located in the folder C:\Windows\system32\wbem:

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