Extend Disk Partition Windows Server 2003 R2

Windows Server 2003 R2 disk partition size is allocated cautiously when building Server. Once the hard disk is installed on your Windows Server 2003 R2 and divided into several partitions with certain allocated space, the partition size cannot be changed unless you can repartition the hard disk. However, you may meet the problem that disk partition size cannot meet your needs any more when more and more data is stored on the partition. When disk partition is running out of disk space on Windows Server 2003 R2, do you always need to repartition the hard disk?
