Problem of hiding subfolder from domain name (Joomla website)

I tried to redirect my Joomla website located under a "subfolder" to "www.example.com". I want to hide my "subfolder" from my URL. I'd tried "Redirect" from cPanel, and it works when type in www.example.com, but all the links from my website still shows "www.example.com/subfolder".

This is the result that I'm looking for:
www.hoomie.com.au/studio -> www.hoomie.com.au

I want to hide "studio", but showing the page alias is fine.
Correct: www.hoomie.com.au/about
Incorrect: www.hoomie.com.au/studio/about

Can anyone help? Appreciated!!!
