C Drive Runs on Low Disk Space on Windows Server VMware

"I need to expand C drive in Windows Server 2003 VMware. Diskpart command said that the selected drive cannot be extended. My brother told me that I can only extend NTFS data volume with Diskpart. I cannot extend C drive by using Diskpart because operating system is installed on this partition and it is FAT32 file system. However, how can I increase the size of C drive in Windows Server 2003 VMware when Diskpart failed?"

"My PC is running ESX 3.5 with Windows Server 2008 64bit OS. Recently, the C drive in VMware is running out of disk space, so I want to extend the C drive space. But Diskpart command is unable to extend a system partition and Disk Management extend volume is grayed out when I want to extend C drive. Is there any other solution for C drive extending in Windows Server 2008 VMware?"

Why Diskpart Cannot Extend C Drive

First of all, Diskpart command cannot extend system partition; instead, it can only extend data volume. As you know, operating system is usually installed on C drive. Therefore, you may fail to extend C drive by relying on Diskpart command.
In addition, Diskpart can only support NTFS partition. Even if it is data partition, Diskpart cannot extend it if its file system is FAT32.
Finally, Diskpart cannot move partition. If there is no unallocated space behind the partition you want to extend, you still cannot extend the selected partition.
If you run into any of limitation mentioned above, you cannot extend a partition by using Diskpart command.
