Win32_Share class

The Win32_Share class represents a shared resource on a computer system running Windows. This may be a disk drive, printer, interprocess communication, or other sharable device. For more information about retrieving WMI classes, see Retrieving a Class.

The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties. Properties and methods are in alphabetic order, not MOF order.

Members

The Win32_Share class has these types of members:

Methods

The Win32_Share class has these methods.

Method Description
Create Class method that initiates sharing for a server resource.
Delete Class method that deletes a share name from a server's list of shared resources, disconnecting connections to the shared resource.
GetAccessMask Returns the access rights to the share held by the user or group on whose behalf the instance is returned. You should use this method in place of the AccessMask property, which is always NULL.
SetShareInfo Class method that sets the parameters of a shared resource.

 

Properties

The Win32_Share class has these properties.

AccessMask

Data type: uint32

Access type: Read-only

Qualifiers: DEPRECATED

This property is obsolete and is no longer used. Use the Win32_Share.GetAccessMask method instead. The value of the AccessMask property is set to null by WMI. For more information about setting access when a share is created, see the Create method.

AllowMaximum

Data type: boolean

Access type: Read-only

Qualifiers: MappingStrings ("Win32API|Network Management Structures|SHARE_INFO_502|shi502_max_uses")

Number of concurrent users for this resource has been limited. If True, the value in the MaximumAllowed property is ignored.

Caption

Data type: string

Access type: Read-only

Qualifiers: MaxLen (64), DisplayName ("Caption")

A short textual description of the object.

This property is inherited from CIM_ManagedSystemElement.

Description

Data type: string

Access type: Read-only

Qualifiers: DisplayName ("Description")

A textual description of the object.

This property is inherited from CIM_ManagedSystemElement.

InstallDate

Data type: datetime

Access type: Read-only

Qualifiers: MappingStrings ("MIF.DMTF|ComponentID|001.5"), DisplayName ("Install Date")

Indicates when the object was installed. Lack of a value does not indicate that the object is not installed.

This property is inherited from CIM_ManagedSystemElement.

MaximumAllowed

Data type: uint32

Access type: Read-only

Qualifiers: MappingStrings ("Win32API|Network Management Structures|SHARE_INFO_502|shi502_max_uses")

Limit on the maximum number of users allowed to use this resource concurrently. The value is only valid if the AllowMaximum property is set to FALSE.

Name

Data type: string

Access type: Read-only

Qualifiers: key, Override ("Name"), MappingStrings ("Win32API|Network Management Structures|SHARE_INFO_1|shi1_netname")

Alias given to a path set up as a share on a computer system running Windows.

Windows 2008 example: "\SERVER01\public" - Windows Server 2008 requires that you place the UNC in the name.

Path

Data type: string

Access type: Read-only

Qualifiers: MappingStrings ("Win32API|Network Management Structures|SHARE_INFO_502|shi502_path")

Local path of the Windows share.

Example: "C:\Program Files"

Status

Data type: string

Access type: Read-only

Qualifiers: MaxLen (10), DisplayName ("Status")

String that indicates the current status of the object. Operational and non-operational status can be defined. Operational status can include "OK", "Degraded", and "Pred Fail". "Pred Fail" indicates that an element is functioning properly, but is predicting a failure (for example, a SMART-enabled hard disk drive).

Non-operational status can include "Error", "Starting", "Stopping", and "Service". "Service" can apply during disk mirror-resilvering, reloading a user permissions list, or other administrative work. Not all such work is online, but the managed element is neither "OK" nor in one of the other states.

This property is inherited from CIM_ManagedSystemElement.

Values include the following:

OK ("OK")

Error ("Error")

Degraded ("Degraded")

Unknown ("Unknown")

Pred Fail ("Pred Fail")

Starting ("Starting")

Stopping ("Stopping")

Service ("Service")

Stressed ("Stressed")

NonRecover ("NonRecover")

No Contact ("No Contact")

Lost Comm ("Lost Comm")

Type

Data type: uint32

Access type: Read-only

Qualifiers: MappingStrings ("Win32API|Network Management Structures|SHARE_INFO_502|shi502_type")

Type of resource being shared. Types include: disk drives, print queues, interprocess communications (IPC), and general devices.

Disk Drive (0)

Print Queue (1)

Device (2)

IPC (3)

Disk Drive Admin (2147483648)

Print Queue Admin (2147483649)

Device Admin (2147483650)

IPC Admin (2147483651)

Remarks

The Win32_Share class is derived from CIM_LogicalElement.

The Create method in this class is a static method. The Delete, GetAccessMask and SetShareInfo methods are all instance methods.

Depending on your security permissions, you may not be able to retrieve all of the properties of this class. For example, AllowMaximum, MaximumAllowed, Path, and Type properties may return null. Generally speaking, Power Users and Administrators will be able to retrieve all property values.

Examples

The following PowerShell sample displays the shares on the local system.

$shares = Get-WMIObject -class Win32_share
"Shares on : {0}" -f $((gwmi win32_computersystem).name)
$shares | sort name | ft -auto

Alternately, if you wish to filter more precisely, you can use the following PowerShell snippet:

gwmi -q "SELECT * FROM Win32_Share WHERE Name != 'ADMIN$' AND Name != 'IPC$'"

The Following VBScript sample displays the shares on the local system.

strComputer = "." 
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\CIMV2") 
Set colItems = objWMIService.ExecQuery("SELECT * FROM Win32_Share")


For Each objItem in colItems 
 Wscript.Echo "Name: " & objItem.Name
 Wscript.Echo "Caption: " & objItem.Caption & "=" & objItem.Path
Next
