Mouzi is an open-source desktop application designed to automatically organize files in the Downloads folder by file type and custom rules. The tool operates silently in the system tray, monitoring selected folders and moving new files to designated subfolders according to user-defined criteria. It aims to eliminate clutter and manual sorting, providing a streamlined solution for users who frequently download and manage files.
Key features include customizable sorting rules based on file extensions, regular expressions, and dynamic destination paths using placeholders such as year, month, or filename. Mouzi supports undo functionality, allowing users to reverse any file movement with a single click through its locally stored history log. The application also provides an instant "clean now" option to organize existing files in the Downloads folder within seconds. To enhance usability, Mouzi displays subtle toast notifications when actions are performed, which can be clicked to access the destination folder immediately. It supports six languages—English, Polish, Italian, German, French, and Russian—and automatically detects the system language.
Privacy is a core aspect of Mouzi’s design. All data, including file names, sorting rules, and history, is stored locally in a SQLite database, with no information ever leaving the user's computer. The tool does not use cloud services or telemetry. Built with Rust and Tauri, Mouzi is optimized for minimal memory and CPU usage, ensuring it runs unobtrusively in the background. It includes safeguards such as a grace period and file-lock detection to prevent moving files that are still downloading, reducing the risk of broken downloads.
Mouzi is available for Windows 10, 11, and various Linux distributions, with installation options including auto installers, MSI packages for enterprise deployments, portable executables, AppImage, DEB, and RPM packages. The application is free to use, distributed under the MIT License, and its source code is publicly accessible. Mouzi is suitable for individuals seeking an automated, privacy-focused solution to keep their Downloads folder organized without manual intervention.
