Windows Server 2016 built-in partition manager
The Windows Server 2016 has built-in partition manager--Disk Management and Diskpart. Disk Management can help people use the interface to manage disks, partitions or volumes, while Diskpart manages them with command line.
Disk Management of Windows Server 2016 has many utilities, such as extend/shrink volume, format partition, change drive letter and paths for partitions, delete partition, convert basic disk to dynamic disk and so on. But it has many restrictions of Disk Management. The Extend Volume function, which can help you extend partition only when there is an unallocated space adjacent to it and on the right side, if not, the Extend Volume option would be grayed out. The Shrink Volume function, which can shrink the partition for you, but if there is an unmovable file at the end of the partition, even the partition is nearly empty, the Shrink Volume would be grayed out. Thus, you cannot use the Extend/Shrink Volume to resize partition.
Diskpart is another partition manager in Windows Server 2016. To use it, you must know clearly about Windows Server Diskpart command syntax. Because once it executed, it cannot be revoked, and once you make mistakes, it may cause a big damage to the business. So, if you are not familiar with the syntax, we truly suggest you do not use the command line of Diskpart to manage partitions.
