A new system shell, which is (in some regards) stronger than even Windows Command prompt, made in pure C. This terminal is fairly new, and doesn't require any complex installing process. You just download it, and then immediately use it! HTerminal has an improved console interface with modern buttons. It only has 28 commands, but it is useful none the less! And, if you're already reading this, then why not give it a try? It is completely free and takes up less than 1 MB of space + you don't even have to install it. It is ready to be used the second you download it! And, worst case scenario, you just stop using it. And if you enjoy our app, give it a rating, and maybe tell us about newly discovered bugs! It is much appreciated because it gives feedback that helps us improve HTerminal for you.
