How to extend a data volume in Windows Server 2003

Diskpart command line works fine to extend data volume in Windows Server 2003, commands are simple, but if you don't get used to non-graphic interface, Partition Extender is the best option. Unlike other partition manager software, Partition Extender will not first shrink large sized volume, make unallocated space, and finally goes to extend volume steps; it will extend target partition directly and can be freely operated by the handle.

Like the below screenshot, unallocated space is behind D Drive, far from C Drive, normal partition software will ask you to Click D Drive first, and move unallocated space from the end of D partition to the head of D Drive, or the end of C Drive, and ask you to click C Drive again, to extend C Drive, and Confirm. The theory is right although, a little more steps on simple mission. How about I just make one click on the partition I want to extend and it works?


Well, that's Partition Extender, that's exactly how Partition Extender works when Extend boot partition or data partition. Click target partition and extend, it makes theory come true.
