How to Shrink Partition in Windows 10

Updated on Aug 19, 2019 by Brithny to Partition Master

When you want to shrink a partition, there are three ways available for you. You can use Disk Management, professional partition management tool or DiskPart Command. Based on your needs and habits, choose the way you prefer to shrink a partition on Windows 10 following the detailed guide below.

Shrinking a partition is needed when you want to create a new volume or extend another volume on the same disk. In most of the cases, you can shrink partition directly without worrying about data loss. However, if you want to shrink a RAW partition, you may destroy the files in it. Thus, if the partition you want to shrink has a RAW file system, you are recommended to perform RAW data recovery, and then carry out one of the methods below to shrink your Windows 10 partition.

3 Ways to Shrink Partition in Windows 10

Generally, users use three ways to shrink Windows 10 partition, Disk Management, third-party software, or DiskPart.

Method 1. Shrink Partition with Windows 10 Built-In Disk Management

Windows 10 built-in Disk Management enables you to view and manage your disk drives. It has the ability to shrink volume and extend volume.

Step 1. Right-click on "This PC", choose "Manage", and choose "Disk Management" in the pop-up window.

Step 2. Then you need to right-click on the partition which you want to shrink, and choose "Shrink Volume..."

Step 3. In the dialog box, set the amount of space to shink and click "Shrink".

Step 4. After shrinking the partition, you will create more free space on your disk. Then you can create a new volume or extend a partition as you like.

With Disk Management, you can only shrink a RAW partition or NTFS partition on a basic volume. Thus, if the target partition falls outside the category, you need to use one of the two other ways to shrink partition in Windows 10.

The Bottom Line

As you can see from the details above, using Disk Management and EaseUS partition tool is much easier than using DiskPart. However, there are limits on the partition you can resize while using Disk Management. Thus, EaseUS Partition Master can meet the needs of more users. Besides, after the shrink operation, most of you will create a new partition or extend an existing partition. If you want to extend a partition with non-adjacent space, using a third-party tool is your only choice because Disk Management don't support such operations.
