Teleport Pro is a fully automated, multithreaded, link-following, file-retrieving webspider. It will retrieve all the files you want - and only the files you want - from any part of the Internet. Teleport Pro can completely copy a website, enabling you to 'offline browse' the site at much greater speeds than if you were to browse the site online; search a website for files of a certain type (and even size); and make exact duplicates of websites. Version 1.44 may include unspecified updates, enhancements, or bug fixes.
Editor's review of Teleport Pro

This software not only downloads entire Web sites to your hard drive, it also can download parts of any site and search a site by keyword or filename. Teleport Pro copies an entire site to a location you specify, and the software is highly configurable. During download, the program constantly displays how many files it has found, how many are downloaded, and how many remain.

Browsing the downloaded pages works well. If you try to view something that wasn't downloaded, the program will display a message saying that it wasn't copied to the hard disk. The performance of the program matches the quality of its organization. If you're looking for an offline browser, give Teleport Pro a try.
