Simple Download Manager is a lightweight, professional Java application designed to streamline and take full control of your file downloads. Built for power users who value efficiency, it offers a clean interface with advanced features that go far beyond standard browser capabilities.
- Smart Queue Management: Automatically manages multiple downloads with a built-in queue system (max 3 concurrent), ensuring optimal bandwidth usage without overloading your connection.
- Advanced Drag & Drop: Instantly import links by dragging them from your browser, or drop a text/CSV file to process hundreds of URLs at once with zero interface lag.
- Intelligent Status Reporting: The "Status" column provides real-time feedback, distinguishing between standard states and specific issues like not found file, disk full, or too Many redirects.
- Smart Auto-Retry: Features a built-in recovery system that attempts to resume failed downloads every 10 seconds, stopping intelligently after 3 failed attempts or on irreversible errors.
- In-Depth Analytics: Track instantaneous speed, average session speed, total elapsed time, and a stable ETA (Estimated Time of Arrival) based on your connection's performance.
- Selective Export & Backup: Easily save your entire list or just the active queue to text files, making it simple to migrate pending tasks between devices.
- Desktop Integration: Includes a "Double-Click to Open" feature for completed files, a "Minimize to Tray" mode for background work, and custom system icons for a professional look.
- Portable & Private: No installation required, no tracking, and no cloud-syncing. Your data and download history remain strictly local and under your control.
- Cross-platform: Native look and feel on Windows, macOS, and Linux thanks to the modern FlatLaf UI library (Java Runtime required).
Important: You need a Java Runtime Environment (JRE) installed on your system to run this app. You can download it for free at Adoptium.net. Other compatible versions (like Azul, Amazon Corretto, or Oracle) are also supported.
