Extend volume grayed out windows 10

The space in your C drive is getting full and you thought of extending the drive . When you go to disk management and tried for extend option you see the option disabled or grayed. Why?

It is because there is no unallocated space next to your C drive.

You can extend any drive from disk management only when there is contiguous unallocated space available next to your target drive. That means the unallocated space which is not partitioned and does not have any drive letter is not next to your target drive. You can view your disk partitions from disk management.

You can try shrinking the drive next to your target drive and then allocate the space created to the target drive. But hold on.

The unallocated space that is created by shrinking the next drive is never on the right side of the the target drive and thus you cannot extend your drive from disk management . The unallocated partition is always created to the right of the drive from where it was shrunk and created.

For example if you want to extend your C drive and in D drive there is space available to shrink. You shrink the D drive, an unallocated space is created just next to D drive not to your C drive.

Extend volume is disabled for C drive

As you are unable to extend your C partition from disk management , one option left is to delete the partition D which is next to C drive, and create an unallocated space next to C drive. But do you really want to delete your D partition? You will loose your data from D drive.

It is not possible to move the unallocated space that you have just created to the right adjacent side of C drive from disk management tool and thus you cannot extend your C drive.
