My C: drive has only 13 GB free out of 231 GB, and this is preventing me from installing software needed for my computer science projects. My D: drive has about 106 GB free out of 224 GB. Both drives may actually be partitions on the same 512 GB SSD. Can I safely move some of the space from D: to C:, and what is the safest way to do it?

First confirm whether C: and D: are partitions on the same physical SSD or separate drives. If they are partitions on one 512 GB disk, you can potentially enlarge C:, but the unallocated space must be directly next to it. Back up important files first, then use Windows Disk Management or a reputable partition manager. You may need to move or delete D: before extending C:, so do not remove D: until anything important has been copied elsewhere.
Another option is to move a large folder from C: to D: and create a directory junction so Windows still finds it at the original location. This can work for some data folders, but backups are essential, and it is better to avoid doing this with system folders or applications unless you know exactly what they contain.
Before changing partitions, consider moving your Documents, Downloads, Pictures, and other personal folders to D:. You can also install large applications and development tools there when the installer allows it. This frees space on C: without risking the partition layout.
You can extend C: only when there is unallocated space immediately after the C: partition. Simply shrinking D: usually creates the free space at the end of D:, not beside C:, so D: may need to be moved with a partition tool. Make a full backup first, because an interruption or mistake could make the partitions inaccessible.
I checked and they are partitions on a single 512 GB SSD. D: mainly contains temporary files, so I can clear it, but I want to make sure I follow the correct steps before changing the partitions.
