I have a question, and I am sorry if I don't perfectly articulate it and have any sort of propriety in doing so--I am frantic, right now! In my "downloads" folder, I had a desktop icon that I didn't find necessary being there. So, I deleted it. Now, I have lost all of my files on my desktop, most notably my transfer letter to RPI. I tried to do a system restore, but it had no effect. What should I do?
