Filelight
Filelight helps users find disk space to free by showing usage as concentric rings. It scans local, remote, or removable disks and displays details about files and folders; users can delete selected files or folders from the application. Scans can cover files and folders, including external drives, but Filelight does not show application sizes. Users can exclude chosen folders, remote filesystems, or removable media from scans. For remote filesystems such as NFS or Samba mounts, the handbook warns that scanning can generate high network traffic. Filelight integrates with the Dolphin, Konqueror, and Krusader file managers, and it supports configurable color schemes and scanning and appearance settings. It can also be launched from a command line with a folder name to scan that folder. Linux users can install it through Discover or another AppStream store, a distribution package manager, or Flathub. Filelight is free, with a free plan, and runs on Linux and Windows.
