Detailed Description

The Write-VolumeCache cmdlet writes the file system cache to disk. By default, Windows caches file data to be written to disk in a special memory area before writing the data to disk.

This cmdlet enables you to forcibly empty, or flush, the write cache by writing it to disk.

Parameters

-AsJob

-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.

-DriveLetter<Char[]>

Specifies an array of letters that identify one or more drives or volumes in the system. The cmdlet writes the volume cache for the drives or volumes you specify.

-FileSystemLabel<String[]>

Specifies an array of file system labels. The cmdlet writes the volume cache for the file system labels you specify.

-InputObject<CimInstance[]>

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

-ObjectId<String[]>

Specifies an array of IDs, as strings. The ID is not globally unique.

-PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

-Path<String[]>

Specifies an array of paths. The cmdlet writes the volume cache for the paths you specify.

-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 PowerShell® 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, -OutBuffer, and -OutVariable. For more information, see    about_CommonParameters (https://go.microsoft.com/fwlink/p/?LinkID=113216).

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

• Microsoft.Management.Infrastructure.CimInstance#ROOT/Microsoft/Windows/Storage/MSFT_Volume

  You can use the pipeline operator to pass an array of MSFT_Volume objects to the InputObject parameter.

Outputs

The output type is the type of the objects that the cmdlet emits.

• Microsoft.Management.Infrastructure.CimInstance#ROOT/Microsoft/Windows/Storage/MSFT_Volume

  If you specify the Passthru parameter, this cmdlet returns an object representing the volumes for which you wrote the file system cache to disk.

Notes

• 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.
