Open-Source Alternatives to TreeSize

dua-cli is a cross-platform terminal-based disk usage analyzer and cleanup utility. It scans directories in parallel using thread pools to compute and display disk space consumption faster than sequential traversal, then lets users navigate the results interactively and delete unwanted files with safety measures. The tool distinguishes itself through a multi-step deletion confirmation process that requires user approval before permanently removing files, with an optional trash integration that moves deleted items to the system trash instead of performing irreversible removal. It reads setting

WinDirStat is a disk usage visualizer and storage analysis tool designed to scan drives and represent file and folder sizes. It functions as a system for calculating subtree sizes and identifying storage bottlenecks on a local file system. The utility distinguishes itself through a proportional treemap and an interactive directory tree, where the area of each block corresponds to the size of the file. It utilizes an extension-based color mapping system to categorize data types visually and provides a reporter that aggregates storage consumption by file type. The software covers broad storage

gdu is a command line disk usage analyzer and interactive disk profiler used to scan directories and visualize space consumption across file systems. It functions as a file system management tool that allows for the identification and removal of large files and folders to free up storage. The tool features a cursor-based interface for navigating directory structures and archives. It provides a storage cleanup workflow that enables the deletion of selected items directly from the analysis view, utilizing parallel execution to reduce I/O wait times. The application supports recursive directory

Dust is a command line disk usage analyzer written in Rust. It functions as a disk space visualization tool and recursive directory size scanner used to identify large files and directories through a formatted list of disk consumption across a filesystem. The tool differentiates itself by providing a recursive tree view to visualize space distribution and the ability to output directory and file size data in machine-readable formats for external processing and analysis. Its broader capabilities include filesystem auditing and storage capacity management. This is achieved through file and dir

Lemon-cleaner is a macOS system cleaner and resource monitor. It provides a suite of tools for removing application junk and temporary files, completely uninstalling software and its hidden support files, and reclaiming disk space through a visual disk space analyzer and duplicate file remover. The project distinguishes itself with specialized capabilities for digital media decluttering, utilizing visual similarity analysis to identify and prune redundant photos. It also includes a system resource monitor that tracks real-time hardware metrics, such as CPU temperature and memory usage, direct

Czkawka is a cross-platform utility designed for storage optimization and filesystem maintenance. It functions as a comprehensive file analysis engine that identifies redundant data, including duplicate files, empty directories, broken symbolic links, and temporary files. By utilizing hash-based content verification, the tool ensures accurate identification of duplicates regardless of file names or metadata. The project distinguishes itself by offering both a native graphical user interface and a command-line interface, allowing for both interactive management and automated, headless system m

lsd is a directory listing tool and directory tree visualizer designed as a modern replacement for the standard Unix ls command. It provides a command line interface for listing directory contents and visualizing hierarchical folder structures with enhanced visual formatting. The utility distinguishes itself through customizable themes, allowing users to modify the output appearance by mapping specific colors and icons to file names, types, or extensions. It uses extension-based icon mapping to provide visual file type identification via specific glyphs. The tool covers functional domains in

Mole is a terminal-based utility designed for comprehensive system maintenance, storage management, and real-time hardware monitoring. It provides a command-line interface for users to analyze disk usage, track system health metrics, and perform routine optimization tasks to maintain machine stability and performance. The project distinguishes itself through a declarative configuration model that uses structured data files to define custom cleanup logic, allowing for precise control over the removal of temporary files and project artifacts. It incorporates a safety-first execution layer that

CleanMyWechat is a desktop application disk utility designed to reclaim storage space by cleaning cached images, videos, and files from the WeChat desktop client on Windows and macOS. It functions as an automated cache maintenance tool that identifies and removes unnecessary media assets from communication software caches. The utility optimizes media storage by filtering assets based on file type and age thresholds while preserving conversation text history. To prevent permanent data loss, it utilizes a recovery system that moves identified files to the system recycle bin rather than erasing

Duf is a command-line utility designed to provide a comprehensive overview of disk usage and filesystem statistics. It functions as a terminal-based system monitor that retrieves and displays real-time metrics for mounted devices, including capacity, usage, and inode information. The tool distinguishes itself through a responsive terminal-aware layout engine that automatically adjusts to console dimensions and supports custom color themes based on usage thresholds. It provides granular control over data presentation, allowing users to filter filesystem reports by device, mount point, or type,

mac-cleanup-sh is a command-line utility designed for macOS that automates the removal of temporary files, system logs, and application caches. It functions as a system maintenance tool to reclaim storage capacity by identifying and purging redundant data across the operating system and development environments.
