“I tried to extend my C drive at Disk Management yesterday , but I find the extend volume grayed out at Disk Management on my Windows 10 system. What’s the problem? Can I extend the partition when the extend volume greyed out?”
This can be a common situation for Windows users, no matter for Windows 11/10/8/7/XP/Vista, or Windows server system, extend volume option greyed out will cause users much trouble managing the hard disk partitions. Why does this problem happen?
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.
When the Extend Volume option on your computer grayed out, you want to extend the partition, “Shrink Volume” will not work since the shrinked unallocated space is not adjacent to the target partition.
What can you do to enable the extend volume on Windows 10?
Delete volume which is next to the target partition to make some unallocated space.
If the deleted volume makes free space on your computer instead of the unallocated space, you may delete the free space with free tool Partition Resizer to convert the free space to unallocated space.
The free space is from a logical drive that cannot be extended to c drive which is primary drive. You need to convert the free space to unallocated space at first.
