I managed to screw some stuff up - so I did an archive and install to get things running nice and smooth again. Everything is back to normal. However, I have a 10GB Previous Systems folder. I want my space back. So what happens if I delete this folder? I want to keep all of my applications and documents. Are they contained in this Previous Systems folder? I'm fine with losing settings because I'll just re-set everything. I'm pretty sure the archive and install reinstalled iLife, and other essential apps as well. So can I delete the old ones that are in the Previous System? Any help is tremendously appreciated! Thanks!
