Why is the Extend Volume option grayed out and unavailable in Windows 10 Disk Management?
In Disk Management, I want to merge a 20GB unallocated space into the adjacent E drive, but the “Extend Volume” option is grayed out and unavailable, preventing direct operation. I need to understand...
The unallocated space must be directly next to the drive or partition you want to extend. If there is any other partition between them, you cannot extend the volume directly.
