My laptop has an 80GB hard disk, and Norton N360 backs it up to an external 160GB disk. I recently moved my iTunes folder off of my laptop and onto the external hard disk to free up some space, and I noticed this morning that I had an error saying that the external disk was full. My iTunes folder is around 25GB in size, but the Norton 360 folder is now over 110GB. How can that be, if my laptop is only 80GB? I need to free up space ASAP on my external disk as it is showing as only having 32KB of free space! Any ideas anyone?
