WebSurfer Assistant is a smart Internet client for downloading files, set of pages or sites wholly. It supports error recovery and download resuming. If the downloading of files was not completed during one Internet session, WebSurfer Assistant will continue downloading during the following sessions. The program will begin to download the large file from the same position, in which the downloading of this file in the previous session was interrupted. WebSurfer Assistant replaces the external hyperlinks in the downloaded pages with the local links, so the downloaded pages can be looked through in an off-line mode.
