You can either use shrink or delete to create unallocated space
Caution – Use delete only if you are ok to lose the data in that target drive or you have backed up that drive already.
If you are ok to delete the D: drive you may not require any third-party software – you will get unallocated space immediately after C: drive and you are good to extend.
