Hello, my HDD has 2 partitions: C/ for OS and D/ for games and multimedia. I want to re-install Windows 7 OS on C/, but Steam, Origin and other games are installed in D/. What will happen to all my games after the install? Will I have to re-download all of them? I put them on D/ because the system runs faster that way since all I have to do over time is defragment C/ only, not the entire HDD.
