Get-SmbOpenFile

Get-SmbOpenFile [[-FileId] <UInt64[]>] [[-SessionId] <UInt64[]>] [[-ClientComputerName] <String[]>][[-ClientUserName] <String[]>] [[-ScopeName] <String[]>] [[-ClusterNodeName] <String[]>] [-CimSession<CimSession[]>] [-IncludeHidden] [-SmbInstance {Default | CSV}] [-ThrottleLimit <Int32>] [<CommonParameters>]

The Get-SmbOpenFile cmdlet retrieves basic information about the files that are open on behalf of the clients of the Server Message Block (SMB) server.

Parameters

-CimSession [<CimSession[]>]

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

-ClientComputerName [<String[]>]

Accepts pipeline input ByPropertyName

Specifies the filters for the returned open files so that only files opened from the specified client computer are returned.

-ClientUserName [<String[]>]

Accepts pipeline input ByPropertyName

Specifies the name of the user whose open files are retrieved.

-ClusterNodeName [<String[]>]

Accepts pipeline input ByPropertyName

Specifies, in the case of a share hosted by a windows cluster, the name of the server which hosts the open files that are retrieved.

-FileId [<UInt64[]>]

Accepts pipeline input ByPropertyName

Specifies the file identifier (ID) of the file for which the information is retrieved.

-IncludeHidden [<SwitchParameter>]

Indicates that handles that are created and used internally are enumerated also.

-ScopeName [<String[]>]

Accepts pipeline input ByPropertyName

Specifies the scope of the open files that are retrieved.

-SessionId [<UInt64[]>]

Accepts pipeline input ByPropertyName

Specifies a session ID. This cmdlet returns only files that have been opened in the specified session.

-SmbInstance [<Microsoft.PowerShell.Cmdletization.GeneratedTypes.SmbShare.SmbInstance>]

Accepts pipeline input ByPropertyName

Specifies the input to this cmdlet. You can use this parameter, or you can pipe the input to this cmdlet.

-ThrottleLimit [<Int32>]

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShellr calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

<CommonParameters>

This cmdlet supports the common parameters: Verbose, Debug,ErrorAction, ErrorVariable, WarningAction, WarningVariable,OutBuffer, PipelineVariable, and OutVariable.

Inputs

None

Outputs

Microsoft.Management.Infrastructure.CimInstance#root/Microsoft/Windows/SMB/MSFT_SmbOpenFile

The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object. This cmdlet return a MSFT_SmbOpenFile object that represents the files opened on the SMB server.
