Apps with 'HDD Visualization' feature

  1. WizTree scans your entire hard drive and shows you which files and folders are using the most disk space. It does this VERY QUICKLY. In fact, we believe WizTree to be the fastest application of this type currently available!
  2. Space Radar is a disk and memory space visualization app built with Electron and D3.js. It currently supports Sunburst, Treemap, and Flamegraph charts and is available for Mac and Windows.
