After the Windows 11 upgrade, the C drive may have less free space. Then, you may need to extend the C drive in Windows 11. This post from MiniTool shows you how to extend partition Windows 11 .

Why Do You Need to Extend Partition Windows 11?

Windows 11 is the latest major release of Microsoft's Windows NT operating system, released in October 2021. It is a free upgrade to Windows 10. Therefore, most people will upgrade their PCs to Windows 11 if the PC meets the Windows 11 system requirements .

However, Windows 11 requires more storage than Windows 10. Windows 10 requires at least 32GB storage while Windows 11 requires at least 64GB storage. After users upgrade from Windows 10 to Windows 11 , they may find that the C drive doesn’t have enough free space. This will drop PC performance. In this case, they need to extend C drive Windows 11.

In addition, if your PC has separate data partitions, you may also want to extend them when they are full.

Something You Can Try Before Extending Partition Windows 11

If your C drive or data partitions are full, the most direct solution is to transfer important personal files to other places (cloud storage or external storage) or delete unnecessary files.

If you have tried the above methods, but the partition is still full, you can try extending partition Windows 11.

How to Extend Volume Windows 11

In this part, I will show you how to extend partition Windows 11 using 5 ways. The fifth way is the best because it can avoid data loss.

  2. Use Windows Disk Management.

Preparatory Work (Optional)

If you want to use the first four tools, which are built in Windows 11, you should do the preparatory work, because these tools have the same limit: There should be adjacent unallocated space behind the partition you want to extend .

If there is no unallocated space or the unallocated space is not adjacent to or behind the partition you want to extend, you will encounter the Windows 11 Extend Volume not enabled issue.

If your PC has a second disk (a data disk) and you want to extend a partition on the data disk, the Extend Volume won’t be grayed out as long as there is unallocated space, but it will convert the disk into a dynamic one automatically.

If your PC has only one disk (the system disk) or you don’t want to convert the disk to a dynamic one, to get adjacent unallocated space behind the partition you want to extend, the most common way is to delete the partition that is adjacent to and behind the partition you want to extend.

To delete the adjacent partition, you can refer to the following 2 cases.

Case 1. The adjacent partition is a data partition.

If there is important data on the partition, please back up it to another drive first.
