I've got an SSD that I'm using for my main drive. I recently received a warning that my drive was almost full (1.2GB free). I did some standard cleaning, but then found that I had 60GB of space getting chewed up in my caches, 30GB in prefs and 17GB in my Mail folder. I'd like to "flush" a lot of that stuff, if possible. I've optimized everything else that I needed to space-wise. Does anyone have any recommendations for some software to do that? Or can I just dump a lot of that manually? Cheers.
