Is there anyway to change the layout of the sub domain prefix I have a domain social.irlmusic.net is there anyway to make it irlmusic.net/social without having to install the script with in the top level domain?

Create the subdomain and point it to the subfolder as the root directory.

Sorry but how do you mean?

Apache, IIS, something else

cPanel, plesk, something else?

I run Apache on linux with cPanel, and had set up subdomains in cPanel. E.g. milk.example.com.

What I found when I went into my server directory structure was a directory named milk, which contained an .htaccess file in its root, a cgi-bin folder and a copy of my error pages in there.

Your best bet is probably to place a redirect in the root of milk.example.com pointing to example.com/milky/ or example.com/milk2/. Were you to redirect milk.example.com to example.com/milk/, and you could access that folder, it would redirect you in an endless loop.

Been awhile since I dumped my subdomain approach.
