Hey! Yesterday, I had 60GB free on my main hard drive - last night my computer was overrun with nieces/nephews who all decided to (using another user account) use the Mac for a few hours... This morning, I have 400MB free and my Mac is grinding to a halt!! I have tried searching for all files > 1GB in size, all files that were created yesterday etc etc - and nothing untowards comes up... I think I have tried all of the usual things like emptying trash etc - but I cannot for the life of me see how 60GB could have simply disappeared in 24 hours - it must be something the kids did - but all they said they did was browse the net and take a few photo's / messed about in photo booth... my first thought was that they'd recorded several hours of video - but I can't see anything in there... any ideas what else I can do to find out where my disk space has gone!!???
