Hi guys, 2 hours ago I (secure) deleted a whole bunch of stuff off my macbook and emptied the trash. I went from 35GB free to 37GB free. I left me room to come back two hours later to a message saying 'Startup disk nearly full', and having checked my disk, I now have zero KB left. How has this happened considering I haven't installed anything new? What should I do? All help is greatly appreciated. Thanks.
