External hard drives/storage systems So I've heard that people can plug in USB drives, run some kind of software, and it acts like extra hard drive space. I'm running out of memory from all the shows I've download and I'm still downloading more. My C: drive is where I have all my games and my D: drive is where all my shows are, both have less than 50GB left. And what kinds of hardware can I buy to increase memory space? No, I'm not buying another computer.
