Recently I have been trying to back up my old computer by creating a system image and saving it to an external hard drive to boot from. After many hours I discovered making an external USB drive mimic a local disk is a lot more complex than I originally thought it would be. Therefore, what is the best program to use for copping my personal files from my windows 8 PC into my windows 10 PC? I tried Macrium Reflect however when I tried to re-access some of my video files they came out corrupted with no video. I am open to any recommendations.
