- Download large files using IDM (Internet Download Manager) on Windows. Use when user wants to download files via URL and prefers IDM, or explicitly requests IDM downloading. Ideal for large files (hundreds of MB to several GB). Triggers on requests like "download this file with IDM", "use IDM to download", "IDM下载", "用IDM下载文件".
IDM Downloader
Use IDM (Internet Download Manager) to download large files via COM interface or command line on Windows. Recommended for large files such as datasets, videos, disk images, and archives where download resumption and acceleration are beneficial.
