how do you uninstall the whole component?

I tried to search but couldn't find answer. I like the component but no one ever bought anything. i want to uninstall the component and every part of it to save space. No point in it just sitting there. Will you say how? Thanks

Thanks for the help. When you write "you need to uninstall HikaShop, then ..." I assume you mean the component itself. And to remove it you go to Extension Manager list and just delete it? And only then I would do the same thing for the modules and then the plugins -- in that order? Also I assume this should be problem free and not affect any of the rest of my site.

Thanks again.

I've now uninstalled component and all modules and plugins. I'm going to the Tables via phpmyadmin. I see many with jos_hikashop_x. Are these the ones, and are there any others?

O.K. Thanks. It's done.
