Why Diskpart Cannot Extend C Drive on Server 2012?

Diskpart cannot extend volume on Windows Server 2012, but why you failed to extend C drive by running Diskpart command? If you want to rely on Diskpart command to extend a partition, one of the most important things is that unallocated space is always needed. If there is no existing unallocated space, you need to squeeze some from other partitions on the same hard disk. When there is unallocated space, you still need to move it close to the partition you need to extend. The other important point is that Diskpart command only supports to extend NTFS data volume. In the other words, if the partition you want to extend is system partition or has FAT32 file system, Diskpart will fail to extend the partition.

Free up Disk Space on C Drive

Usually, C drive is also known as system partition, so you cannot simply delete files to free up disk space on C Partition. But you can run Windows built-in disk cleanup tool to delete some Internet temporary files, cookies and caches, etc to free up disk space on C drive. In addition, you can uninstall some unnecessary programs. Many people would like to install programs on C drive. When they do not want to use the program, they just simply delete the program. As a matter of fact, if you want to delete a program from your PC, you should uninstall it. If you just simply delete it from Desktop, it cannot delete the program completely and it will still occupy disk space.
