Filelight vs LumaDisk

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.

LumaDisk is a disk space analyzer for macOS and Windows that maps a filesystem to show what is using storage. Its interactive sunburst and treemap views update during a scan. The app groups regenerable developer folders such as node_modules, /target,.next, and DerivedData, and groups duplicate files with one copy selected to keep. It also lists files of at least 100 MB that have not been opened for six months, a year, or two years. External drives are fully supported; network volumes can be analyzed read-only. Cloud support includes iCloud Drive, OneDrive, and Dropbox, while Google Drive is described as coming soon. The free plan keeps scanning and the sunburst view available. A LumaDisk license is listed at $6.89 a month, billed as a one-time payment rather than a subscription, and covers up to five Macs. Requirements are macOS 12 or later on Apple Silicon, or Windows 10 or later on x86-64 or ARM64. Reclaim permanently deletes files, with a ten-second undo window and safeguards against queuing system folders.
