I'm having problems dragging and dropping files on my macbook. I'm currently trying to move files from my harddive onto my external because I'm running out of space. I'm worried I may have deleted an important file by accident and now have lost the ablity to drag and drop. Is there any way I can fix this? I would take my macbook into an Apple store to tak to someone in person, but there is none nearby. Any insight into the problem would be greatly appreciated! Also, I'd like to add that I'm not very computer savvy, so if there is a solution, I'd really appreciate it if the explanation isn't full of computer jargon. Thanks!
