I have very recently moved a large amount of files from my computer and external hard drives to a larger external hard drive and now my computer is massively slow. Even in opening basic programs like Word. To my knowledge I didn't move any programs. Just movies and music. Any ideas why it would do this? Oh and how would I change where my media player searches for music, because since moving it I can't get any of it to play from the new hard drive. Also since moving the files my mouse is also running very slow as if it's not registering when I move it.
