Extending C drive

Question

Extending C drive

Chandrika Ravishankar 6

I have windows 10 and unable to get updates as my C drive is full. I have lot of space in my D and G drive and want to move it to C Drive. I know I can extend my C drive from the other two drives. My question is how do I bring the G drive next to C drive in my Disk management. See attached image of my disk management screen.

You need to have adjacent free space, or use a 3rd party tool.

Start by running cleanmgr and get rid of unneeded files.

Run Treesize Free and see what's using up your C drive space.

With only 120GB on your disk, that's not a lot. I have never tried to extend C across 2 hard drives, so I can't say how well that's going to work. That site looks like it can be done, but I don't know if I'd risk it. The last time I had a really small C drive, I bought a new 1TB drive and reinstalled the OS.

Thanks MotoX80. Appreciate the time you took to respond.

I read elsewhere that if I bring the G drive next to C drive in my disk management, then I will be able t extend the C drive As you can see from the image there is a healthy EFI system in between.

Is this possible ?

I don't think so. It is my understanding that you can extend the C drive only to adjacent free space. That would mean you would have to delete these partitions. And that isn't give you much additional space anyway.

https://www.hdd-tool.com/windows-10/extend-c-drive-windows-10.html

Extend volume C with other disk
If there is no other partition, or not enough unused space in all other partitions on the same disk, NO partitioning software can extend a partition by taking space from another separated hard disk.

However, there's still a way with NIUBI Partition Editor by cloning this disk to another larger one. You can extend partition C and other data volumes with extra disk space. Watch the video how to expand C drive by cloning:

https://www.partitionwizard.com/partitionmanager/extend-c-drive.html

To extend C drive, there must be unallocated space adjacent to the C drive. Otherwise, you cannot extend C drive.

Have you analyzed what folders are using up the most space? Did you run cleanmgr?

You can use MiniTool Partition Wizard (the free version)
It has more options to move or resize partitions than default MS DM

I tried the MiniTool Partition Wizard. The problem is Drive C is under Disk 2 and drives D and G (where there is space available to move) are in Disk 1. How do I move G drive to Disk 2 so that I can extend the C drive from G drive ?

The way I read those links that I posted... you can't. If you got rid of the 3 recovery partitions, then you could extend C into that space. But that would only add about 14 gb of space.

@Castorix31 have you ever tried anything like this? My experience is mostly with extending RAID-5 data partitions.
