While you can change your partition layout it is slow and you may then find moving an extra 50GB from D to C was too much (you are not using this new space on C and so it is wasted) or too little (you have to do it again for some more).
Have a look with Treesize Free and see what is taking the space. You can also move OneDrive, Video, Pictures etc in the same manner. Perhaps you could just move some data from C to D - perhaps by moving your Documents folders : Documents Folder - Move Location in Windows 10 | Tutorials You could shrink D with disk management and then use some software like partition wizard to move your D partition a bit to the right, then extend C but it would be slow as all of the data on D would have to be moved.ġ00GB should be fine for C.
You can only extend a volume to the right hand side. No you can't without third party software.
