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
Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.
Parameter properties

| Default value: | None |
| Supports wildcards: | False |
| DontShow: | False |
Parameter sets
(All)
| Position: | Named |
| Mandatory: | False |
| Value from pipeline: | False |
| Value from pipeline by property name: | False |
| Value from remaining arguments: | 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-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.
Parameter properties
| Type: | CimSession[] |
| Default value: | None |
| Supports wildcards: | False |
| DontShow: | False |
| Aliases: | Session |
Parameter sets
(All)

| Mandatory: | False |
| Value from pipeline: | False |
| Value from pipeline by property name: | False |
| Value from remaining arguments: | 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.
Parameter properties

| Position: | 0 |
| Mandatory: | True |
| Value from pipeline: | False |
| Value from pipeline by property name: | True |
| Value from remaining arguments: | False |
-FileSystemLabel
Specifies an array of file system labels. The cmdlet writes the volume cache for the file system labels you specify.
Parameter properties
| Type: | String[] |
| Default value: | None |
| Supports wildcards: | False |
| DontShow: | False |
Parameter sets
ByLabel
| Position: | Named |
| Mandatory: | True |
| Value from pipeline: | False |
| Value from pipeline by property name: | True |
| Value from remaining arguments: | False |
-InputObject
Specifies the input object that is used in a pipeline command.
Parameter properties
| Type: | CimInstance[] |
| Default value: | None |
| Supports wildcards: | False |
| DontShow: | False |
Parameter sets
InputObject (cdxml)
| Position: | Named |
| Mandatory: | True |
| Value from pipeline: | True |
| Value from pipeline by property name: | False |
| Value from remaining arguments: | False |
-ObjectId
Specifies an array of IDs, as strings. The ID is not globally unique.
Parameter properties
| Type: | String[] |
| Default value: | None |
| Supports wildcards: | False |
| DontShow: | False |
| Aliases: | Id |
Parameter sets
ById
| Position: | Named |
| Mandatory: | True |
| Value from pipeline: | False |
| Value from pipeline by property name: | True |
| Value from remaining arguments: | False |
-PassThru
Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.
Parameter properties
| Type: | SwitchParameter |
| Default value: | None |
| Supports wildcards: | False |
| DontShow: | False |
Parameter sets
(All)
| Position: | Named |
| Mandatory: | False |
| Value from pipeline: | False |
| Value from pipeline by property name: | False |
| Value from remaining arguments: | False |
-Path
Specifies an array of paths. The cmdlet writes the volume cache for the paths you specify.
Parameter properties
| Type: | String[] |
| Default value: | None |
| Supports wildcards: | False |
| DontShow: | False |
Parameter sets
ByPaths
| Position: | Named |
| Mandatory: | True |
| Value from pipeline: | False |
| Value from pipeline by property name: | True |
| Value from remaining arguments: | 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.
Parameter properties
| Type: | Int32 |
| Default value: | None |
| Supports wildcards: | False |
| DontShow: | False |
Parameter sets
(All)
| Position: | Named |
| Mandatory: | False |
| Value from pipeline: | False |
| Value from pipeline by property name: | False |
| Value from remaining arguments: | False |
CommonParameters
This cmdlet supports the common parameters: -Debug, -ErrorAction, -ErrorVariable, -InformationAction, -InformationVariable, -OutBuffer, -OutVariable, -PipelineVariable, -ProgressAction, -Verbose, -WarningAction, and -WarningVariable. For more information, see about_CommonParameters.
Inputs
CimInstance
You can use the pipeline operator to pass an array of MSFT_Volume objects to the InputObject parameter.
Outputs
CimInstance
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
- When used in Failover Cluster, cmdlets from the Storage module operate on cluster level (all servers in the cluster).
