Move Unallocated space on Windows 10

Unallocated space is blank and it does not belong to any drive. Besides creating new volumes, you can add Unallocated space to C drive or any data volumes to increase partition size. Windows 10 provides Disk Management snap-in to do some basic operation to disk partitions. Besides deleting a drive, you can get Unallocated space by shrinking a volume in Disk Management.

The most common issue in Windows 10 is C drive getting full, so many people try to shrink D and extend C drive with the built-in Shrink Volume and Extend Volume in Disk Management. After shrinking D drive, the Unallocated space cannot be added to C drive, because Extend Volume is greyed out. In fact, this problem can be solved easily by moving Unallocated space next to C drive.

In this article, I’ll introduce how to move Unallocated space in Windows 10 (32 and 64 bit) without losing data. With NIUBI Partition Editor, you can move Unallocated space to C drive or move to the right or end of a drive. In my Windows 10 laptop, there are several volumes plus an 10GB Unallocated space in Disk 0. Le’ts see how to move the Unallocated space to other locations.

Move Unallocated space to C drive

As I said above, most of people want to shrink D to extend C drive, but it is impossible in Windows 10 Disk Management. Extend Volume works only when there is adjacent Unallocated space on the right side, but the Unallocated space that shrank from D is not adjacent to C drive. Extend Volume will be enabled if you can move Unallocated space next to C drive.

Steps to move Unallocated space to C drive in Windows 10:

NIUBI Partition Editor

Step 1: Right click drive D and select Resize/Move Volume, drag middle position rightwards.
