This program provides a similar functionality as the well-known WGet and cURL tools. However, in contrast to those, INetGet is based directly on the "native" Windows Internet programming interface (WinINet). This comes at the advantage that INetGet is very small and lightweight, as it uses the HTTP(S) and FTP services provided by the operating system, instead of having to implement these protocols on its own. There are no external dependencies (e.g. OpenSSL or GnuTLS), except for standard system libraries that are present on every Windows system anyway. Still, advanced features, such as HTTPS and IPv6, are supported.

Furthermore, since INetGet is based on the Windows crypto libraries, it uses the Windows certificate store. This means that, in contrast the aforementioned tools, you do not need to provide and maintain your own certificate bundle for HTTPS. Certificate updates as well as security fixes for the underlying cryptographic routines are automatically provided, via Windows Update. On the downside, you will have to trust Microsoft's protocol implementations. And the availability of some features depends on the Windows version.
