I built a new PC which has a 2 TB SSD with a fresh install of Windows. I have a new 4 TB SSD as well which I want to use as a secondary drive. I would like to copy the files on my two 1 TB SSDs in my old PC onto this 4 TB SSD. How do I do this? What program should I use? Will there be any problems caused by the old Windows files onto this new drive? Is there a way to avoid copying those files?
