Filelight allows you to understand exactly where your diskspace is being used by graphically representating your filesystem as a set of concentric segmented-rings.
It is like a pie-chart, but the segments nest, allowing you to see both which directories take up all your space, and which directories and files inside those directories are the real culprits.
You can use it to locate hotspots of disk usage and then manipulate those areas using a file manager.
Key Features
- Specify a directory to scan on startup at the command line.
- Scan across fileysystem boundaries including remote filesytems and removable media.
- Integated with Konqueror under View | View Mode | RadialMap View.
- Exclude directories.
