Updated on Aug 16, 2019 by Daisy to Partition Master

Summary:
Do you know how to use unallocated space in Windows 10? Many people are seeing unallocated space in a local hard disk or external hard disk but have no idea what to do with it. This tutorial is going to help you make full use of such free space, by means of creating a new partition or adding it to an existing partition as you want.

How to Use Unallocated Space in Windows 10

Unallocated space, as the name suggests, it's part of disk space that is not allocated to any partition. A computer describes any physical space on a hard drive that doesn't belong to a partition as unallocated. This means that no programs can write data to this space, nor save data until it's being a part of the real disk partitions. To put the space into normal use, you have two options: [1] create a new partition; [2] extend an existing partition.

Where does unallocated space come from? Generally, to get unallocated space there are two scenarios. One, you deleted a partition; two, you shrank a partition. You won't see unallocated space in Windows Explorer, only find that a hard drive is showing less space than actual, for example, 1TB shows 700GB. 

On a Windows 10 computer, The most versatile hard disk management utility is called Disk Management, and it's also where you come across unallocated space. Before getting to know how to use Windows 10 Disk Management to manage the unallocated space, it's good to know what it can do & what it cannot do.

  • It CAN create a new partition on unallocated space. 
  • It CANNOT change the location of unallocated space, neither add the unallocated space to a non-adjacent partition as well as the right-adjacent partition.

That is to say, for my case, I can only move the unallocated space to G drive. If I want to increase E drive, or if there is another Drive K on the right side, Disk Management cannot help.
