If you have a PC or laptop just upgrade to Windows 11, you may see a low disk space warning if you do not have enough capacity to save new files and applications. In this case, you may want to explore expanding the partition to better manage your data. Microsoft has included an “Extend Volume” tool to the built-in Disk Management application to help with this.

It implies you may utilize the Disk Management option in Windows 11 to expand a partition. This program is commonly used to manage disk partitions. However, many users may be dismayed to see the option to Extend Volume greyed out in Windows 11.

Why is the extend volume not enabled in Windows 11?

When the system drive in Windows 11 is completely full, you can relocate or transfer your files and applications to free up some disk space. It may be expanded with unallocated space on the hard disk. But here’s the thing. The “Extend Volume” option in the Disk Management tool is only accessible when adjacent unallocated space in the volume to be extended is available. As a result, the option to enlarge volume was greyed off in Windows 11 for the following reasons:

◤ 1. The hard drive partition you wish to extend does not use the NTFS file system. Because when there is a RAW or NTFS partition, Microsoft only activates the Extend Volume option in the Disk Management.

◤ 2. There is no unallocated contiguous space on the right of the primary partition that you want to extend.

◤ 3. When there is no unallocated space on dynamic drives.

So, if you insist to use Disk Management to extend your C drive, then you’ll have to delete the drive next to the C drive.
