There is not enough space in my C drive to download new programs. And I found my D drive is empty. C drive is where the operating system installed, so generally, C drive needs to be allocated with enough space and we should not install other third-party programs in it.
If you can't extend volume, like cannot extend volume in C drive, don't worry. You'll find why is the Extend Volume option greyed out on your computer: There is no unallocated space on your hard drive. There is no contiguous unallocated space or free space behind the partition you want to extend.
First, you need to open Disk Management through the Run window by pressing the Windows key + R at the same time, then enter 'diskmgmt. msc' and click 'OK'. Once Disk Management has loaded, right click on the C drive, and select the Extend Volume option to extend the C drive with the unallocated space.
As here is no unallocated space after the C partition drive, so extend volume greyed out. You need to have an “unallocated disk space” to the right of the PartitionVolume you wish to extend on the same drive. Only when “unallocated disk space” is available “extend” option is highlighted or available.
Step 1: Download NIUBI Partition Editor, right click D: drive and select "Resize/Move Volume", drag the middle towards right in the pop-up window. Then Unallocated space is moved next to C drive. Step 2: Right click C: drive and select "Resize/Move Volume" again, drag right border towards right in the pop-up window.
