Hi, I've been reading this forum for a while now, and after using the imac at work I decided I'd give it a go so bought a refurb MacBook. So far, it's not going great. I've actually crashed it twice in two hours of using it. I've also managed to generate a 25GB hidden file in my /Users folder called ".andrew". My username is "andrew" if that has anything to do with it. I also have filevault if that makes a difference. What is this file likely to be? Can I delete it safely? Also, is there anyway of viewing hidden files in Finder? I had to use JDisk reporter to find the offending file Apart from that I'm liking it. Everything works nicely and no major problems. Edit: or is it a folder with a file in it? how do you tell?
