I have been thinking about updating from Windows 8 to 8.1 for a long while now, but I do not know if it is safe. I have heard of so many people who lost their files after updating, but that was a long time ago. Do you still lose your files? If so, I am not updating, because I have Battlefield 4, with all DLCs, so it will be near to impossible to make a backup of my personal files. I also make minecraft videos, and I have over 50 Gigabytes of videos on my computer that I don't want to lose. I want to be sure that it is 100% safe before I update, can anyone help me out?
