How to move Unallocated space in Windows 10

Updated on: November 16, 2019

This article introduces how to move Unallocated space on Windows 10 (32/64 bit). Move Unallocated partition to left, right or end of disk without losing data.

Unallocated space can be used to create new volume or expand other partitions. To get Unallocated space, you may either delete or shrink a partition. Windows 10 native Disk Management tool can help you create, delete, format, shrink and extend partition, but it can't move partition or Unallocated space.

Can't move Unallocated space in Windows 10 DM

Why many people want to move Unallocated space in Windows 10? The most common reason is that Extend Volume function can't expand partition with non adjacent Unallocated space.

Windows 10 Disk Management has advanced Shrink Volume and Extend Volume function to resize partition without losing data. Thus, when a partition is running out of space, many people try to extend it by shrinking another volume. However, it is impossible because of the inherent limitations of Disk Management.

Shrink Volume can only make Unallocated space on the right side. Extend Volume can only merge Unallocated space to the left contiguous partition. So after shrinking drive D, Extend Volume is always greyed out for other partitions

In this situation, if you can move Unallocated space to the left side of D or right side of drive E, Extend Volume will be enabled to these two partitions. To do this, Disk Management cannot help you, you need professional partition manager software such as NIUBI Partition Editor.

It sounds easy, but there is potential data loss risk if you use some unreliable partition software.

Better than other tools, NIUBI Partition Editor has advanced file-moving algorithm, so it saves much time when moving partition and Unallocated space. In addition, it provides unique 1 Second Rollback, Cancel-at-well and Virtual Mode technologies to help resize and move partitions safely.

How to move Unallocated space to left

Download NIUBI Partition Editor and you'll see all disk partitions and detailed parameters. Unallocated space is on the right side of drive D:


Right click drive D and select "Resize/Move Volume", drag middle position rightwards in the pop-up window.

Move drive D

Then Unallocated space is moved to the left side of volume D.

Move Unallocated

How to move Unallocated partition to right

If you right click the Unallocated space with either Disk Management or NIUBI PE, you can create new volume but there is no "move" option. From step above, if you want to move Unallocated to left side of D, you should right click partition D.

Similarly, if you want to move Unallocated space to right of E drive, you need to right click E and select "Resize/Move Volume". Different with above method, you should drag middle position towards left in the pop-up window:

Move drive E

If you want to extend E drive with the left contiguous Unallocated space, you can merge it into E drive directly without moving Unallocated to the right side.

Right click E and select "Resize/Move Volume", drag left border towards left to combine Unallocated space:

Extend drive E

How to move Unallocated space to end of disk

If you want to move Unallocated space to the end of disk to create new volume or because of some other reasons, simply right click drive E, F, etc. to move one by one.

If you want to move Unallocated space to other disk, it is impossible. Because a hard disk is a physical unit, no partition software can combine or move Unallocated space to another separated disk.

If you want to extend a partition but there is no other drive in the same disk, you can clone this disk to a larger one with NIUBI Partition Editor. While cloning, you can expand this partition with extra disk space.
