by John, Updated on: April 8, 2022

The same with previous versions, Windows 11 computer also runs low disk space on C drive. Many people ask whether it's possible to extend partition in Windows 11 without losing data. Nobody likes to reinstall operating system and tons of programs. The answer is yes. To extend volume in Windows 11 laptop/desktop/tablet, you may try either Windows native Disk Management tool or third party software. In this article, I'll introduce 3 ways to extend Windows 11 partition with both kinds of tools. This problem can be solved easily no matter how your disk partition is configured. You don't have to try all 3 methods, just select the corresponding method according to your own disk partition configuration.

Extend volume in Windows 11 Disk Management by deleting

The first method is not suggested, because you have to delete partition. This method is only used by the users that don't like to use third party software and the disk partition configuration meets the requirements below:

  1. There's a contiguous partition on the right of the drive that you want to extend, and you must delete it to get contiguous Unallocated space.
  2. The partition to be extended must be formatted with NTFS file system.
  3. The partitions to be deleted and extended must be the same Primary or Logical drive.

In most of Windows 11 computers, users want to extend system partition C, and C drive is always and NTFS Primary, that means:

  1. There's a contiguous partition D (or E) on the same disk and you can delete it.
  2. This contiguous drive D: (or E:) must be a Primary partition.

If there are no programs installed in this contiguous Primary partition and you can delete it, then you can extend C drive partition without any software.

How to extend partition in Windows 11 with native Disk Management:

  1. Right click Windows logo on taskbar on the bottom, select Disk Management in the list.
  2. Right click the right contiguous partition (such as D:) and select Delete Volume option.
  3. Right click the left contiguous partition (such as C:) and select Extend Volume option, simply click Next till Finish in next windows.

If your disk partition configuration doesn't meet the requirements or if you don't want to delete any partition, you have to run disk partition software. If you want to extend Windows 11 volume by shrinking another one, Disk Management cannot help you. Learn why cannot extend C drive in Windows 11 Disk Management.

Extend Windows 11 volume with free partition software by shrinking

You won't lose data by shrinking a partition, therefore it's better than deleting. Windows Disk Management has "Shrink Volume" function, but it can only make Unallocated space on the right while shrinking a partition. This Unallocated space can't be extended to any other partition with "Extend Volume" function. Better than Disk Management, NIUBI Partition Editor can make Unallocated space on either left or right when shrinking a volume. Furthermore, it can move Unallocated space and extend it to any partition on the same disk, no matter this partition is contiguous or not.

There are many disk partition software to help you shrink and extend partition in Windows 11 computer, but few are safe enough. In fact, even Windows Disk Management is not 100% safe, especially when there are both Primary and Logical partitions on a disk. Therefore, you'd better make a backup first and run safe partitioning software.

Better than other tools, NIUBI Partition Editor has powerful Virtual Mode, Cancel-at-well and 1-Second Rollback technologies to protect your system and data. It has free edition for Windows 11/10/8/7/Vista/XP home computer users. To shrink and extend partition in Windows 11 computer, you just need to click, drag and drop on the disk map.

How to extend volume in Windows 11 laptop/desktop/tablet with NIUBI:

  1. Right click a partition (such as D:) and select "Resize/Move Volume" option. In the pop-up window, drag either border towards the other one. The difference is, if you drag left border towards right, Unallocated space will be made on the left.
  2. If you want to extend system partition C, make Unallocated space on the left in step 1. Right click C drive and run "Resize/Move Volume" again, then drag right border towards right to combine this Unallocated space.
  3. Click Apply on top left to take effect.

If you want to shrink E drive to extend nonadjacent partition C, there's an additional step to move partition D to the right and make Unallocated space next to C drive.
