Question How to expand the size of DYNAMIC C: drive in Win 10 without losing Data?

[rose27]

My C: drive is full. How can I add 50 GB space to it from D: which has 100 GB free space?
Remember that both are DYNAMIC, not Basic.
I can't find any proper video in Youtube.

Disk Management image is here. In it, D: is not adjacent to C:.

"without losing data" means you first and second step is to make 2 full copies of everything.

There are multiple ways that however you do this, it can go wrong.

If it were me, I would start over completely.
Multiple Dynamic partitions, incl the C, on a single drive is a bad place to be in.

Add to that, your physical drives are much too full.

Wow! 94MB free on boot drive C:. I like to keep at least 10GB free on my Windows boot drives. A typical Windows Update can use up 3 to 5GB of disk space.

I'm surprised you manage to run Windows with such limited free space. The first thing I'd try is Disk Clean-up and choose the option to clean System Files, then move at least 5GB of files off drive C:, before expanding the partition. If necessary, temporarily uninstall a big program. You might not be able to backup your files until Windows has more free disk space.
