aux. harddrive shortcut/sendto,

I installed a larger aux hardisk drive in my p.c. I can store a lot of my
files and documents on to it .however;sometimes,most of the time when I try
to delete the files or documents off my main drive C: (to try and manage
space) I get an accsess denied message.Also is there an easier way to SendTo
files and documents to my aux drive other than drag n drop.Is there a way to
SendTo drive D:???
