Best thing to do is plug in your new 2TB into your PC and set it say as the D Drive. Then do this

For all your folders in your user folder but move them to the D Drive (I like to just change the C to a D so that on the D drive it still keeps the D:\users\Yourusername\Folder structure). This will move a bulk of your files to the new 2TB drive.
If you have a lot of games i would uninstall them off the C Drive. We need to get the C Drive below 250GB. Then you can Power down, plug in the SSD, and then boot back into windows, install Macrium Reflect and clone your current C Drive to your new SSD drive.
Once cloned, shutdown your PC, disconnect your 1TB, power on, go into BIOS, set SSD and primary Boot, and then see if it boots and it should keep the user folders mapped to the D Drive as well. Now all your documnets, downloads, etc will be saved on the 2TB and not take up space on the SSD.
I would install small games that you don't care about load times to the 2TB Drive and if you want the speed install the game to the SSD if you have space.
Me I have a 240Gb in my desktop and that is it. Nothing more. All my files are stored and pointed to my server. I just install games as I play them which is only one or two at a time.
