Reasons Why Extend Volume Grayed out Windows 11/10/8.1/7

People would like choose Disk Management to manage the disk partition when they want to extend, shrink, format the partitions. You can right-click the “Computer”, choose “Manage” to go, then you can enter “Disk Management”. There are all your disk partitions listed. You can choose the partition you need to manage, right click it, choose “Extend Volume”, “Shrink Volume”, “Format Volume”, etc. If you see the Extend Volume option grayed out on your computer, it means that there is no unallocated space on your hard disk. In this situation, you need to spare some free space first, then you can extend your partitions.

Besides no adjacent free space, here are some other causes for extend volume greyed out in disk management.

• The target partition is not NTFS filesystem

• The free/unallocated space is far away from the volume you want to expand, non-adjacent free space
• The disk is MBR not GPT...
