WINDOWS 2000 PROFESSIONAL
When a disk nears capacity, you can take several steps to alleviate the space crunch. One of your options is to resize the partition.
If the disk contains unallocated space or a second partition that isn't near capacity, you can resize the crowded partition to increase the volume size and make more space available on the disk.
One of the more popular commercial partitioning applications is PowerQuest's PartitionMagic. The latest version of PartitionMagic can resize NTFS partitions on the fly without requiring a reboot.
