Move Unallocated space on Windows 10

This article introduces how to move Unallocated space in Windows 10 (32/64 bit) without losing data. Drag and drop to move Unallocated partition next to C drive or end of disk.

Unallocated is blank disk space and not belong to any drive, you can get Unallocated space by deleting or shrinking a volume in Windows 10 Disk Management. Besides creating new volumes, you can add Unallocated space to C drive or any data volumes to increase partition size. However, to accomplish this task, you need 3rd party partition software.

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, but it is impossible. After shrinking D drive, Unallocated space is nonadjacent to C drive, so Extend Volume is greyed out. In this situation, you need to move Unallocated space to the other side, then Extend Volume will be enabled.

In fact, no matter you want to move Unallocated space next to C drive, move rightwards or to the end of disk, it is very easy. In this article, I’ll introduce the easiest way to transfer Unallocated space by dragging and dropping.

In my Windows 10 laptop, there are several volumes plus an 10GB Unallocated space in Disk 0. Le’ts see how to move location of this Unallocated space.
