To extend C Drive

I have installed WIN10 on laptop few days ago. And make NVME SSD partitions of 30 gb and 140 gb. Now want to extend C partion but while checking it in disk management I found 140 gb free partion before C drive. How can I extend C drive without formatting the disk?

Please suggest the solution.

Thanks in advance.

Extending partion in windows 10

I have a Windows 10 box, someone has set up badly. The 640 gig drive, is partitioned into a 15 gig C drive, and a 625 gB D drive. The OS is spread across C and D. Of course C is out of space, I'm trying to install Office 2010. Even though I set office
to install on D, its wanting Space on C.

I used Disk Manger and was able to unallocated 200 gig from D. I was hoping to extend the C partition from 15 to 215 gB with this unallocated space. However, the "extend" option Is grayed out for C. I tried rebooting (when in doubt reboot)

same think, the 200 gig unallocated is there, but, the extend option for C is greed out.

Any suggestions?

Thanks James.
