is a great application for copying the entire contents of a website, and even works well with most security-enabled websites to copy the site's files. BlackWidow employs a Net Spy utility, has support for many languages, even custom ones, and allows site directory browsing, as if you had opened the remote server's files in Windows Explorer. BlackWidow's plug-in system is extensive, and allows the creation of your own custom plug-ins to handle any site that is nefariously difficult. I have been using BlackWidow for some time now to help with web development and security efforts. It makes quick work of downloading all site files.
