I hope I'm in the right forum for this. I'm running Win 10 on a PC with three hard drives, one of 1tb, one of 4 tb, and one of 8 tb. Unfortunately the smallest one is the main one on my computer, i.e. Win 10 is on it. And it's over full with only 61.6 gb free so barely functioning at the moment. My idea is to get one of the others to be the home for Windows and use the other two for storage. But I'm at a loss as to how to accomplish this. I'd appreciate any suggestions as to how to do it or for a better way to attack the problem. Thanks in advance for any advice you can give. On the other hand, if this is the wrong forum for this problem, can you tell me the right one?
