This article introduces how to move space on Windows Server 2012/2016/2019/2022, transfer/move free space from D to C drive in Server 2012 R2 without losing data.
Disk partitions are allocated while installing operating system or by server manufactures. After running the server for a period of time, some partitions may become full. For example: system partition C, exchange and backup partition. Is it possible to move free space to the partition that is getting full? The answer is yes, there are two points you should know:
- Windows inbuilt diskpart command and Disk Management cannot extend volume by shrinking another one.
- There's potential risk of system and partition damage. Back up or clone disk before performing any operations to the server. In addition, run safe software to accomplish this task.
Better than other tools, NIUBI Partition Editor has powerful technologies to protect system and data.
- Virtual Mode - to avoid mistake, all operations are listed as pending for preview, real disk partitions won't be changed until click 'Apply' to confirm.
- Cancel-at-will - if you applied wrong operations, you can cancel the ongoing operations without partition damage.
- 1 Second Rollback - if any error is detected while resizing disk partitions, it can reverts the server to original state automatically in a flash.
- Hot Clone - clone disk partition without server interruption, you may clone the system disk before performing any operation. If system disk fails, you can boot from the cloned disk directly without a long time of recovery.
- Advanced file-moving algorithm - resize and move partition 30% to 300% faster, saving much time especially when there are large number of files.

Move and extend partition with other disk
Note that the free space can only be transferred on the same disk. If you want to move space from another separate disk, it is impossible with any partitioning software. Because the size of a physical disk is fixed. When there's insufficient free space on a disk, copy to a larger one and extend partition with extra disk space. Follow the steps in the video:
