The Resize-Partition cmdlet resizes a partition and the underlying file system.

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.

-DiskId <String[]>

  • This value is required
  • Accepts pipeline input ByPropertyName

Specifies an ID used to identify a disk in the system.

-DiskNumber <UInt32[]>

  • This value is required
  • Accepts pipeline input ByPropertyName

Specifies an array of disk numbers.

-DriveLetter <Char[]>

  • This value is required
  • Accepts pipeline input ByPropertyName

Specifies a letter used to identify a drive or volume in the system.

-Offset <UInt64[]>

  • This value is required
  • Accepts pipeline input ByPropertyName

Specifies the starting offset, in bytes.

-PartitionNumber <UInt32[]>

  • This value is required

Specifies the number of the partition. The number of the partition to be resized.

-PassThru [<SwitchParameter>]

Sends items from the interactive window down the pipeline as input to other cmdlets. By default, this cmdlet does not generate any output.

To send items from the interactive window down the pipeline, click to select the items and then click OK. Shift-click and Ctrl-click are supported.

-Size <UInt64>

  • This value is required

Specifies the size of the partition to create. If not specified, then the number will default to Bytes. The acceptable values for this parameter are: Bytes, KB, MB, GB, or TB. The size may be defined by a user.

-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.

-Confirm [<SwitchParameter>]

  • Default value is false

Prompts you for confirmation before running the cmdlet.Prompts you for confirmation before running the cmdlet.

-WhatIf [<SwitchParameter>]

  • Default value is false

Shows what would happen if the cmdlet runs. The cmdlet is not run.Shows what would happen if the cmdlet runs. The cmdlet is not run.

<CommonParameters>

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

EXAMPLE 1 PS C:\>Get-Partition -DiskNumber 3 -PartitionNumber 2 Disk Number: 3 PartitionNumber DriveLetter Offset Size Type --------------- ----------- ------ ---- ---- 2 D 135266304 931.39 GB Basic Resize the partition to 900GB. PS C:\>Resize-Partition -DiskNumber 3 -PartitionNumber 2 -Size (900GB) The partition is now 900GB. PS C:\>Get-Partition -DiskNumber 3 -PartitionNumber 2 Disk Number: 3 PartitionNumber DriveLetter Offset Size Type --------------- ----------- ------ ---- ---- 2 D 135266304 900 GB Basic Get the partition sizes. PS C:\>$size = (Get-PartitionSupportedSize -DiskNumber 3 -PartitionNumber 2) Resize to the maximum size. PS C:\>Resize-Partition -DiskNumber 3 -PartitionNumber 2 -Size $size.SizeMax This example starts with a 931.39 GB partition.
