Offline Commander lets you download and organize Web pages or entire websites for offline browsing or searching. You can search downloaded websites for keywords using built-in full-text indexing, view directory structure of a website and its sitemap. You can also surf the Internet faster while you are online prefetching specific links with a click of the mouse and record every page you browse with the built-in browser. Offline Commander features a very intuitive user interface, multithreaded web spider, reports, and powerful pattern matching URL filters that you can debug and modify even after a download starts. A very useful feature of Offline Commander lets you fetch multiple links within a text selection with a single click of the mouse.
use Offline Commander most when I find online tutorials, to download them for later use. When using it for the first time you have to look carefully what you need to do, but everything is very clear explained and soon you'll know how it works, and you don't want anything else.
