Filelight vs SpaceMonger

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.

SpaceMonger is a Windows utility for finding and managing storage on PCs and shared networks. It scans and maps files and folders, then displays storage in a treemap to help identify large items. A file-type breakdown and flexible search by size, type, or custom criteria can narrow what to review. Users can build changing cleanup lists and copy, move, or delete files from them. SpaceMonger does not include application sizes in its storage view. Its listed system requirements cover Windows 2000, XP, Vista, 7, 8, 8.1, and 10. The purchase page lists English and Spanish as included languages and 30 days of support. The software is paid, has a 30-day trial, and has no free plan. Stardock says it has operated as a software development company since 1991 and specializes in Windows desktop customization and productivity software.
