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

-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.
