duf vs WinDirStat

Duf is a command-line utility designed to provide a more user-friendly and informative alternative to the traditional 'df' command. It displays disk usage and free space information in a clear and concise manner, making it easier to manage disk space. Duf is highly customizable and supports various output formats, including JSON, CSV, and human-readable text.

WinDirStat is a free, open-source disk usage analyzer for Microsoft Windows that scans drives and folders and shows how disk space is distributed across the file system. It uses multithreaded scanning with direct NTFS support and presents results as sortable lists, extension statistics, a Largest Files view, and an interactive treemap that makes it easy to visually spot which folders and file types are consuming the most space. Beyond basic scanning, WinDirStat can detect duplicate files by content, inspect file permissions, and analyze storage tiers, and it supports file operations like opening, moving, or deleting items directly from the results view. It also offers dark mode, Windows Explorer integration, file-system change monitoring, and scan export, and is distributed under the GNU General Public License version 2 (GPLv2) with source code hosted on GitHub.
