From Calluna Software:
NCollector Studio Lite is an all in one offline browser, website ripper/crawler aimed at home users and professionals needing to download specific files from a website or full websites for offline browsing.
NCollector Studio Lite features the following modes:
Crawl any website for photos, videos, documents or other specific file types using the website crawler mode.
Search mode can be used to download photos, videos etc. by simply specifying a search provider and a search phrase. No other configuration required.
The offline browser mode is able to download a website for offline browsing (when an internet connection is not available for example), or simply to archive a fully functional snapshot of a website.
The mirror mode works the same way as the offline browser mode, only it does not translate the links for offline use, creating an exact snapshot of the source website.
