Index for subdomain

[texas_owl]

I am just getting started. I have set up my first subdomain. Where do I put the index for the subdomain and how do I lable it?

A file named index or default is standard.

Ask your hosting provider where the directory for the subdomain is. Check under your public_html.

I have a index in my public folder for my main domain.
How does the system differentate between the index for my main domain and my sub domain?

By the directory. You could have index.htm in every directory, but you won't.

Ok please let me re state the issue more clearly.
Since I set up my site I have only added files to my PUBLIC_HTML I have created no other directories or foledrs.

For my primary site I have an index.html in my PUBLIC_HTML folder.

Where and how do I put the index for my subdirectory such that when individuals who go to subdirectory.directory.com find the index for the subdirectory?

[Rincewind]

It's common for subdomain.example.com to point to example.com/subdomain. That way you can put all the files related to subdomain into the directory of that name. So the index file for your subdomain would go into the directory that the subdomain poits to.

Thank you so much. I knew it had to be simple but I had been trying to get an answer for 2 days.
Thanks again
