Hello, I've had a 4 GB sleep image on my hard drive for quite some time now. When I first saw it, I researched a little and read that it would disappear as soon as I shut down, but I don't think it has and it seems rather large for a sleep image. I still have about half my HD free, so it's not a pressing matter, just an annoyance. Should I go about getting rid of it or should I let it be? And if the answer is the former, how would I do that? Thanks in advance.
