GetRight is a great utility for downloading files. It's powerful, easy to use, and highly configurable. If you're disconnected, GetRight can resume and complete the download. Also includes multithreading support, mirror searching, download scheduling, custom skin support, audio support, automated retrieval from password-protected FTP sites, default download folders based on file type, automatic daily downloads, automatic virus scans, and more. GetRight can even break large downloads into multithreaded segments to speed the process.
