TreeSize is great because it helps you find where your hard drive space is getting sucked up. Not only is it free, but it is wonderfully illustrative, too. It has saved me lots of money on buying new hard drives and/or bigger hard drives. There’s a paid version that will do network drives – wonderful for sysadmins. But this free utility is great for the power user. Check out TreeSize and download it for free from this site. I highly recommend it. It’s my pick for this week’s Freeware Friday.
