Change your browsers downloads location. First go to D drive and make a new folder named downloads. For instance Firefox... Click on the Orange Firefox button & under.... Options--->Options--->General Tab. From there you need to browse for a new downloads file location under D drive. Typically by default the downloads go to the downloads folder located in your user profile. Such as...C:\Users\Your-Username\Downloads. From there you can move all the files to the new downloads on D if you want. I do it this way myself because I like C drive cleaned up so my backup images aren't so big.
Also another trick is cleanup the drive of dump files etc running disk cleanup. Limit paging to 400-2048 and also disable hibernation. Cmd.exe as administrator and command powercfg -h off this deletes the hidden hiberfil.sys on C: that literally takes up like 10gigs. If you don't use hibernation.
