Yesterday, I installed Windows 7 on my new rig. I downloaded massive files overnight and today, realized that my operating system is in 32 bit (I didn't know it was called x86). So today, I installed Windows 7 in 64 bit. I cannot find my old files, but the hard drive says only 760 GB is free out of 931 GB. Besides the OS, I've only installed drivers. Is it normal to have that many space taken up? Is it my old files in there somewhere? If so, where can I find them?
P.S. I'm aware I did nothing to back up. I'm just wondering why a couple hundred GB are currently occupied.
