[Unsolved] How to add unallocated space to C drive when it’s not adjacent?

I recently noticed that my C drive is running out of space. So, I opened Disk Management and saw that there is some unallocated space on my disk. I thought I could just extend the C drive, but when I right-click on it, the "Extend Volume" option is greyed out.

It seems like the unallocated space is not directly next to the C drive on the right side. I’m not really sure how to move or merge that unallocated space into C drive.

Is there a way to add unallocated space to C drive in this situation? Do I need to use some third-party software, or is there a way to do it with the built-in tools?

    Windows Disk Management only allows extending a partition with contiguous unallocated space on the right side. If your unallocated space is on the left or somewhere in between, Windows won't let you extend C: directly.
