How to Resize Partition in Windows 11 Without Losing Data

by John, Updated on: September 27, 2022

No matter you install Windows 11 by yourself or purchase from a computer seller, the size of all partitions are allocated. But the scheduled partition size no longer meet the requirements after running the computer for a period of time. The typical example is that C drive is running out of space. Many people ask whether it's possible to adjust partition size in Windows 11 without reinstalling OS and programs. The answer is yes. To resize partition in Windows 11 laptop/desktop/tablet computer, you may use Windows native tool or free partition software. This article introduces how to resize Windows 11 partition with both kinds of tools.

Change partition size in Windows 11 with Disk Management

The same with previous Windows 10, Windows 11 has a native Disk Management tool. Besides create, delete and format partition, Disk Management can adjust partition size without losing data (in most cases). However, because of many limitations, Disk Management is not the best tool to help resize Windows 11 partition. Actually, Disk Management can only be used to shrink NTF partition to create new volume, or extend NTFS partition by deleting the contiguous partition on the right side. If you want to extend a volume by shrinking another one, Disk Management cannot help you.

How to resize partition in Windows 11 with Disk Management

To shrink a partition:

  1. Press Windows + X keys together and then click Disk Management.
  2. Right click any NTFS partition and select "Shrink Volume".
  3. Enter an amount of space and then click Shrink button. If you don't enter an amount, the maximum available free space will be used by default.

To extend a partition:

  1. Transfer all files in the right adjacent partition (such as D:) to other place.
  2. Right click this partition and select " Delete Volume", then the disk space will be changed to Unallocated.
  3. Right click the left contiguous partition (such as C:) and select "Extend Volume".
  4. Simply follow up the pop-up Extend Volume Wizard via several clicks.

Restrictions to resize Windows 11 partition with native tool

Firstly, you should know that Disk Management supports NTFS partition only. FAT32 and any other types of partitions can't be resized.

Other limitations to resize partition in Windows 11 via Disk Management:

  1. It cannot shrink partition beyond the point where unmovable files are located.
  2. It can only shrink partition towards left and make Unallocated space on the right.
  3. It can only extend partition when there's contiguous Unallocated space on the right.
  4. It cannot move partition or Unallocated space.
  5. It cannot resize system reserved, EFI and Recovery partition.

The major shortage of Disk Management is that it cannot extend volume by shrinking another one. To do this, you must run third party software.
