Hello, I am a college student, and I own an iMac that is about two years old. I have folders for each semester (always have done so) with sub-folders with each course, and ALL the information that I used in that course. I'm very organized. I trust that I did not make an error. So I went into my folder for my sophomore year (which was two years ago) to find a document that I needed. I opened the sophomore year folder, then the appropriate class within, and THE FOLDER WAS EMPTY, minus ONE document (not the one I needed). I KNOW that I did not delete anything. I hadn't been in that folder...since that year. What could have happened? And no, i doubt that some college buddy logged on to my computer and deleted documents for fun. Like I said, I am very organized, and would not have mis-placed anything.
