Problem with partitions, disks, HDD & SSD

[goswellhd]

I bought a gaming laptop from a friend a few months back. Has a built in SDD and HDD. When downoading a file from chrome, I had no space left - this was news to me. I checked and my C:\ drive is full up, yet my D:\ is 100% free. Essentially I can't download anymore software etc unless I specificially direct it to the D drive. This is no good as I like all my Downloads, Documents, Program Files etc. all to be on the same drive. I'll attach screenshots of my disk management etc so you can see.

Is there any way I can merge these, or a way of transferring all my user data to the D:/ drive. Would this then affect my Microsoft One Drive?

Essentially I'm confused. Any help is great. Many thanks.

(P.s after writing this I transferred a 19 GB file from C to D, hence why I have 19 GB free now).

As seen from the screenshots, I believe Disk 0 is my SSD and Disk 1 is my HDD.

You can't merge C: and D: but there are several things you can do. First start File Explorer, click This PC, right-click C:, then click Properties. Now click Disk cleanup, then click Clean Up System Files. Wait about a minute for it to calculate how much can be freed. When it finishes that, scroll through the list and check the boxes you wish to clean out.
Next you can move library folders Downloads, Documents, and Pictures to that D: drive. From File Explorer, right-click the folder you want to move and follow the on screen instructions.
Bare bones Windows only takes about 20 GB, so there're a lot of possibilities for freeing up more space on the C: drive.

Your file management system is exactly the opposite of mine. I do not want anything at all on my C: drive except the operating system. I have my downloads automatically going to a separate SSD and my pictures and videos on a different SSD. I keep all of my music on an external 8 terabyte hard drive. I feel this arrangement is best to protect my precious data files and yet maintain the integrity of Windows 10.
