Retrieve files using popular internet protocols for free
WGET is a piece of free software from GNU designed to retrieve files using the most popular internet protocols available, including FTP, FTPS, HTTP and HTTPS. Even with large files or mirroring entire websites, retrieving files or mirroring sites is easily done with WGET’s long list of features. It can resume aborted downloads, recursively mirror directories, convert absolute links to relative and more. It also runs on most UNIX-based operating systems in addition to Windows and supports HTTP proxies and cookies, as well as persistent HTTP connections.
