Let me first say I have a Mac, and I'm running a program called DVD copy, which rips and burns dvds very quickly. I love the program. Thing is, when I rip them to my computer, I save the file to the desktop, burn it, and then delete the file from my desktop. For some reason, my harddrive space keeps decreasing and I can't figure out why. I burnt around 10 dvds yesterday, and started out with 25 GB of free harddrive space. Now, i'm down to 13. Are these files somehow hiding themselves on my computer? And where would they be?
