How do i prune the bloat from my system? The smallest i seem to be able to manage to prune my system down is to about 18gb?!! no tunes, pics, extraneous apps(except photoshop and some small utilities). I'm sure most of the files are detritus but how do you know for sure. I want to clone the basic elements of my 80gb powebook drive onto a 20gb ibook drive as a home laptop for the miss. But 18gb leaves nothing. Are there any spring cleaning apps out there ? Any suggestions?
