DESCRIPTION

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.

Accept wildcard characters? false



-DiskNumber <UInt32[]>

Specifies an array of disk numbers.



Required? true

Position? 1

Default value none

Accept pipeline input? True (ByPropertyName)

Accept wildcard characters? false



-DriveLetter <Char[]>

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

Accept wildcard characters? false



-Offset <UInt64[]>

Specifies the starting offset, in bytes.



Required? true

Position? named

Default value none

Accept pipeline input? True (ByPropertyName)

Accept wildcard characters? false



-PartitionNumber <UInt32[]>

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



Required? true

Position? 2

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-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.

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-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.



Required? false

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.
