Filelight vs SizeTrend

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.

SizeTrend is a Windows application for examining disk use across files, folders, and applications. Its scans show application sizes and file-type breakdowns, analyze file contents, and identify duplicates. Search can filter by name, text, binary content, type, size, or date; duplicate detection compares names, sizes, or content. The free edition includes local disk analysis, saved snapshots, and one What Changed comparison when a compatible snapshot exists. A single-file portable download is available, and files or folders can be compressed in place. Professional adds network-folder scans, scheduled scans, automatic storage history, unlimited snapshot comparisons, and exports to HTML, Excel, or CSV. Scans can be scheduled once or run daily, weekly, or monthly through Windows Task Scheduler. Logged-off scheduled tasks cannot access EFS-encrypted files. SizeTrend Professional costs $69.99, paid once, with no subscription and future versions included. Volume pricing is available from five licenses, including per-license rates for larger orders and an unlimited single-site option.
