Windows XP comes with a command-line utility that allows you to manipulate hard drives and partitions. The DiskPart utility, which is short for "Disk Partition," offers the ability to manually resize any partition on the system. You may want to resize a partition to expand the amount of space available to a drive in Windows, or to shrink a drive prior to installing a new copy of Windows on another partition. You'll be able to accomplish the resize with only a few commands.
