I have disk Partitions as C,D,E and F with capacities of 18.63 GB each. I have run out of space on partition 'C' the Primary drive. I wish to extend its volume by poaching on drive 'D' which has 99% free space while other 2 have 85% free space.
By right clicking on drive 'C' in Disk Management screen, the drop down menu shows "extend volume, shrink volume, delete volume etc. Unfortunately 'extend volume' and 'delete volume' cannot be clicked as they are disabled. How can I enable them to perform the required operations for the task.
