Hi. I've just replaced my computer and was pleased to learn I could re-use my old hard drive externally, and that it was very easy to do. I'm intending to use it to store the photos, video, etc. that are already on there, and I'm wondering if it's OK to get rid of "everything else"? The primary reason for this is just to make navigation easier, but, for instance, the "Windows" folder is over 32gb. There's a "SWSETUP" folder that gave me pause when it asked for admin confirmation. Program files, I can't imagine needing any of that if I don't plan to use it, but I haven't done this before and had no luck finding an answer to this particular point. I don't have any of this backed up elsewhere, so I wanted to make sure. Thanks!
