Extend System partition in Windows Server 2003 VMware can improve performance both in VMware and real machine, because VMware shares memory card and processor. So when low disk space warning shows in Server 2003 VMware, it's time to extend system partition and fix this problem, if you ignore this issue, server will become slow or even no response to each single click, not only to the VMware but also infect real machine.

For example, if you install VMware in D Drive with other programs, file explorer in D Drive will crush and other programs cannot be opened smoothly like usual, hard drive in real machine reading and writing speed will decline sharply.

You can extend the whole disk size using VMware settings, but system partition cannot be easily extended in Server 2003 disk management, you had to use diskpart command to extend system partition again. Actually, with server partition software's help, you don't have to reboot server 2003 again and run diskpart tool.

  3. Resize D Drive is to make free space it, unallocated space to be more specific, when this space is created, click C Drive and Resize it;

 Disk Management Failed to Extend Volume

Diskpart is the first option tool to solve low disk space problem in Server 2003 when disk management cannot resize partition and partition software didn't come into being. In real machine, a bootable disc is needed when you want to extend boot volume, we'll test how it works:

Type: list volume >> select volume >> extend.
