So I bought Leopard and received it during the first couple days of it's release. I did the Archive & Install option since lots of people said that was a good way to basically help protect my ass. Now, it's been obviously several months and I still have the files from the Archive from Tiger. Do you think it's safe for me to delete them now? I have a Macbook, 120 gb and I still have 56 gb free but the Archive process took up at least 10 gb from what I can remember. Should I just keep it and only delete it if I manage to be down to sub-10 gb in storage or is it basically worthless to keep now?
