Visualize your hard drive

How to spot RAM offenders, or what data visualization has to do with the workings of your second brain.

Our hard drives are our satellite brains, vital extensions of our intellectual and creative input and output. But our informationally voracious habits also mean that our second brains get inevitably overwhelmed, slowing down and spasming under the weight of our tastes and interests. To combat the issue, here are three fantastic visualization tools — playing on today’s running theme of data visualization — that help declutter your hard drive without requiring any programming knowledge, visually track down what takes the most space and memory, and allowing you to optimize accordingly.

GRAND PERSPECTIVE

GrandPerspective is a Mac OSX utility for graphically showing the file disk usage on your computer using tree map visualizations. It developed by Erwin Bonsma and is released for free as open-source under the GNU General Public License. You can support the project with a donation.

DAISY DISK

DaisyDisk scans your hard drive, as well as any external drives you have mounted, and visualizes the contents as interactive maps, allowing you to easily spot unusually large files and delete or move them to an external hard drive to get more free space. The program’s scanning engine is surprisingly fast even with drives as large as several terabytes. You can get a copy for the rather reasonable $19.99.

DISK INVENTORY X

Disk Inventory X, developed by Tjark Derlien, is very similar to GrandPerspective — same tree map visualizations, also a free download and under a GPL license, also supported by donations — though with a slightly different and more intuitive interface. It was inspired by WinDirStat, the hard drive visualization utility for Windows.
