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.

Examples

Example 1: Write the volume cache

PS C:\>Write-VolumeCache C

This command writes the volume cache for the C: drive.

Parameters

-AsJob

ps_cimcommon_asjob

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-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-CimSessionhttp://go.microsoft.com/fwlink/p/?LinkId=227967 or Get-CimSessionhttp://go.microsoft.com/fwlink/p/?LinkId=227966 cmdlet. The default is the current session on the local computer.

Type:	CimSession[]
Aliases:	Session
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-DriveLetter

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.

Type:	Char[]
Position:	0
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-FileSystemLabel

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

Type:	String[]
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-InputObject

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

Type:	CimInstance[]
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-ObjectId

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

Type:	String[]
Aliases:	Id
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-PassThru

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

Type:	SwitchParameter
Position:	Named

Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-ThrottleLimit

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.

Type:	Int32
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

Inputs

CimInstance

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