🛠️ Detailed Usage Guide

Mastering Varia's basic and advanced features lets you fully leverage this powerful tool:

📥 Basic Download Operations

• Single file download: Click the "Add Download" button in the main interface, paste the URL, and start downloading. You can also drag and drop links into the Varia window to quickly create download tasks.
• Batch downloads: Varia supports managing multiple download tasks simultaneously. You can easily reorder the queue, pause or resume specific tasks without affecting other downloads.
• Browser downloads: After installing the browser extension, simply click download links as usual when browsing — Varia will automatically take over the task.

🚀 Advanced Features

• Speed management: When you need to preserve bandwidth for other network activities, you can set global or per-task speed limits. Enter the settings interface, find the "Speed Limit" option, and input your desired maximum upload/download speed.
• Download scheduling: Varia allows you to set download schedules, such as downloading large files only at night. This is particularly useful for avoiding peak network hours or taking advantage of unlimited time periods.
• Categorized download directories: You can configure different save locations based on file type. For example, videos, documents, and torrents can be automatically saved to separate folders, keeping your downloads organized.

🎥 Video Download Tips

Downloading online videos with Varia is particularly simple:

• Copy the video page URL (not the direct video file link)
• Paste the link into Varia
• Varia automatically detects and offers available format and quality options
• Select your preferences and start the download

This functionality is powered by yt-dlp and supports thousands of sites, including popular platforms like YouTube, Bilibili, Twitter, and more.

🌰 Torrent Download Management

For BT torrent downloads, Varia provides complete support:

• Open a .torrent file or provide a magnet link
• Select a save location
• View included files and choose which specific files to download
• Monitor peer connections and download progress

🔧 Troubleshooting Tips

When encountering download issues, try the following methods:

• Task stuck: Pause and resume the download, or check whether the URL is valid
• Browser integration not working: Ensure the extension is properly installed and check that Varia is running
• Video fails to download: Update the yt-dlp tool, or try switching video quality options

💡 Practical Tips and Best Practices

To fully unleash Varia's potential, here are some practical suggestions:

⚙️ Performance Optimization

• Configure connections wisely: Appropriately increasing connections per server in settings can improve download speed, but setting it too high may cause the server to block you.
• Use scheduled downloads: For large files, schedule downloads during low-usage hours (such as late night) to avoid impacting daily use and potentially gain faster speeds.
• Regular maintenance: Occasionally clean up the completed task list to keep the interface tidy and free up database space.

🔄 Workflow Optimization

• Optimizing browser integration: If some downloads aren't automatically redirected to Varia, try copying the link manually and pasting it into Varia — this method is equally efficient and reliable.
• Multi-task management: When downloading multiple files simultaneously, use priority settings to ensure important files complete first.
• Tag classification system: Add tags to different types of download tasks for easier searching and management later.
