How to allocate space on one disk to another disk to extend the C:

My laptop came with 1TB of space but the majority of it is in the D: drive. I have tried looking everywhere for how to extend the C drive. These are the things I've tried to do/ looked at doing:

-I can't extend the partition because the space is on disk 1 whereas C: is on disk 0

-I could move some of my C: files over, but I have genuinely very little stored in this space. Everything stored on C: (with the exception of 4 apps at 23 GB total) are under 1 GB and a lot of it is stuff for my computer that I doubt I can just 'get rid of' and I'm not technical enough to know exactly what. I don't have any pictures or documents on this computer, or other things that I know would easily be able to be moved to D:

-From my understanding as I've been trying to search for answers, certain things have to be on the C:, so I can't just move everything from C: to D:. I even saw this as I tried to install a program onto D:. I couldn't figure out why it didn't work until I tried to install it on C: and boom, it started working.

If anyone can give me insight on what I can do to fix this problem, I would be very appreciative. All of the solutions I have found involve expanding the partition or clearing files out of C:, both of which I explained above as to why they don't work for my situation or don't help enough to be useful.

    C drive has 2% free. Definitely more than a little on there :-D

    If you only used say 25GB then you should have roughly 150-200GB free which could be at least 75% free probably.

    Hi Parker

    I am Dave, I will help you with this.

    You have a 250Gb (237Gb usable) C drive, the other drives on your system are separate physical drives and so, you cannot ad space fom one of those drives to the C drive.

    2
    You indicate you have very little stored on the C drive, and so, we need to investigate what is using that space and see if that can be cleared.

    Click the link below to download a small free utility called Treesize.

    To run TreeSize, right click its icon and choose Run as Administrator.

    Please provide a screenshot of your C drive in that TreeSize utility, so I can see your hard drive and work out where that space is being used and if there is an underlying problem.
