I find myself having to delete stuff and transfer stuff off of my Macbook at least once a month, mainly because HD video takes up so much room and my 4-year-old computer’s 250 gig HD is just too small to keep up. With that said, you sometimes have no idea where all of your large files are hiding. Once you check the iTunes folder and empty out your old torrent files there are still a lot of nooks and crannies that can be hiding large amounts of data. This is where freeware like Disk Inventory X comes into play. As you can see on my graph most of my storage is taken up by Final Cut Pro and Iphoto. Thanks to this program I can drag my old files onto my external and keep on filling up the laptop.
