I have a new laptop this christmas and it has three drives: Boot, the C drive, Data, the D drive, and Recovery, the E Drive. I assume that Boot is the SSD (solid-state drive) included with the laptop, but I want to make D my "C" drive, as it has exactly 881GB of storage space while my SSD has 120 (118, to be exact).

Basically, whenever Steam asks me to install a game, I always want to install it on the D drive, but I want to make it my primary, main hard drive. I wish to boot from the C drive though, as the name states.

Anyone get what I mean? I just want Program Files and stuff to be on the D drive.
