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

-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.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-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.



Required? true

Position? 1

Default value none

Accept pipeline input? True (ByPropertyName)

Accept wildcard characters? false



-FileSystemLabel <String[]>

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

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
