INetGet is a portable command-line tool that permits downloading files via HTTP(S) or FTP, based on the WinINet API.

With INetGet you will be able to download files via the HTTP (Hypertext Transfer Protocol) or FTP (File Transfer Protocol) protocols, and it offers full support for HTTPS (HTTP over TLS) as well as IPv6. It based on the "native" Windows Internet programming interface (WinINet). These points provide the advantage of making INetGet very lightweight since it uses the HTTP(S) and FTP services provided by the OS, instead of implementing these protocols on its own.

INetGet has no external dependencies (i.e., OpenSSL or GnuTLS), except for standard system libraries present on every Windows system. Since INetGet is based on the Windows crypto libraries, you will find it uses the Windows certificate store. This fact means that you do not need to provide and maintain a certificate bundle for HTTPS. Any certificate updates, as well as security fixes for the underlying cryptographic routines, are automatically provided, via the Windows Update.

INetGet is more geared for users comfortable utilizing the command prompt but is an efficient way to download online content for use at a later time. If you are unfamiliar with command-line commands, then check out The Ultimate List of Every Known Command Prompt Command for some help.
