Actually It is a free, powerful offline browser. A high-speed, multi-threading website download and viewing program. By making multiple simultaneous server requests, BackStreet Browser can quickly download entire website or part of a site including HTML, graphics, Java Applets, sound and other user definable files, and saves all the files in your hard drive, either in their native format, or as a compressed ZIP file and view offline.
After downloading, all links within the website are reconstructed creating a complete hard drive copy of the site that you can view at your own pace without being connected to the Internet. Additionally, BackStreet Browser provides the option of duplicating the original directory structure of a site making it easy to download and transfer a site to another server.
In the event you lose your Internet connection while downloading a site, the Resume Session allows you to pick up a session where you left off after reestablishing your Internet connection. If you wish to update a previously downloaded site, the Update Session feature allows you to revisit a site using new search parameters to make sure you have the most current files.
In addition to the embedded quick-view browser window in the main program screen, you can launch your default browser for viewing any downloaded projects. The quick-view browser window also supports browsing zipped website, so that you don't need to unzip the files to view.
