Drive Sonar, a disk scanner with a second dimension
Drive Sonar is a lightweight disk-space visualizer that scans large file collections and plots file size against modification date.
Field notes
Drive Sonar combines directory scanning with a plot that cross-references file size and modification date, allowing users to look for large, old files rather than only viewing a treemap. The homepage presents a sample scan of 1,243,165 items and reports 108.7 MB median peak memory in its comparison table. It also includes an interactive file explorer, optional text-report export, and confirmed-delete language for moving clutter to the Trash. The listed release is version 0.6.0 under the Apache 2.0 license.
