BlackWidow (Version 4.1 originally reviewed) is a powerful Website scanning tool and an offline browser. It allows users to download an entire site -- including HTML files, images, cgi files, and more -- with the site structure intact. The intuitive, explorer-style interface makes BlackWidow easy to navigate, and users can specify the depth to download, the file types and sizes, wildcards, etc. Features like displaying the external links in the site (broken links and status of links) will be very useful for Webmasters. Users can simultaneously scan and download multiple sites and also monitor the scanning/downloading process using the Threads window. BlackWidow can scan HTTP, SSL, and FTP sites and can be configured to work with proxies and firewalls. BlackWidow is shareware, and a free trial version is available at the site.
