Nobody likes to reinstall operating system and all programs. The answer is yes. To extend volume in Windows 11 laptop/desktop/tablet, you may use either Windows native Disk Management tool or third party software. This article introduces 3 ways to extend volume in Windows 11 computer with both kinds of tools. This problem can be solved easily no matter how your disk partition is configured. You don't need to try all 3 methods, just select the corresponding method according to your own disk partition configuration.

The first method is not suggested, although Disk Management is Windows builtin tool, because you have to delete partition in advance. 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.

Most of Windows 11 computers users want to extend system partition C, C drive is always NTFS and 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 you don't want to delete any volume or the partition layout doesn't meet the requirements, jump to the next section.

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

  1. Right click Windows logo on taskbar on the bottom, select Disk Management in the list.
