Vista’s inbuilt partition manager

Windows Vista includes a built-in functionality in Disk Management to shrink and expand partitions. No more third party utilities needed to do that job.

For shrinking the partition all you have to do is, go to the Disk Management screen, right-click on the partition that you want to shrink, and select “Shrink Volume” from the menu. In the Shrink dialog you will have to enter the amount you want to shrink by.

If you have to extend then in the Disk Management screen, just right-click on the partition that you want to shrink, and select “Extend Volume” from the menu. On this screen, you can specify the amount that you want to increase the partition by. Note that the extend partition feature only works with contiguous space.
