Leech

Leech is a high-speed offline web browser for Windows that downloads web site content to your hard drive. It is a multi-threaded application which allows you to simultaneously "leech" multiple files from a server.

These files are stored on your hard drive and can be viewed later without having to access the Internet. Files can be filtered by file type and size.

Links can be filtered by directory, server, and levels. Additional options allow you to restrict the amount of time and disk space used to save a site.
