Transfer to new drives

[Simon_16]

Hey everyone,
I have a 1TB HDD with all my files, programs and my OS on it. I use my PC mainly for gaming. My HDD is getting low on available space. What I wanted to do was buy a 2TB HDD to have all my data and games on it and an SSD to have ONLY my operating system. I was wondering what could be the easiest thing to do to achieve this. I would like it if I didn't have to reinstall my games, considering I have around 600GB of them and would take HOURS to reinstall. If someone could provide me with all the steps to do so I would greatly appreciate.
Thank you

There's no easy way to do that. Some games may work without reinstalling them and Steam has a utility to help with changing drives and place their games are installed to. Copying files from one HDD to another is relatively easy and fast enough.
