pyLoad: Lightweight Download Manager For One-Click Hosters
pyLoad is a lightweight, cross-platform download manager for one-click file hosting websites such as RapidShare, MegaUpload and many others as well simple http/ftp links.
Among its most important features are captcha recognition, automatic archive extraction and reconnect (useful for most file sharing websites: pyLoad disconnects your Internet connection and then reconnects so you get a new IP so you can continue downloading, bypassing limits imposed by various websites).
