Index.html Showing in Address Bar

Question

Hi everyone,
This is the first time that this happens to me, either I forgot how to fix it or it is a new Markup that is doing it.
In my website, each main page is called index.html and located inside its own folder ... For example:
Folder: about
                    -index.html
Folder: products
                    -index,html
Now everything uploads and works perfect, except that once I click back to home page, the URL shows: www.mysite.com/index.html  and if I click on About us it shows: www.mysite.com/about/index.html
Normally it should just have www.mysite.com/about/
right?
Is there anything that I'm supposed to do to fix this?
I was probably thinking maybe my links should be linking to the folder only (../about/) instead of linking to the page itself.
As we speak, my site just finished uploading with this method mentioned and it works perfectly.
But Now the question is.... is that the right thing to do?
Thank you.

Answer 1

Ok, here we go, now my sites are live and everything works perfect.
Just so I'm clear here: I have the about us page called index inside a
folder called about.
So instead of linking to the index.html, my link was "as Mark said"
../about/   so my URL becomes something like:
www.mysite.com/about/
As for Subdomains, Murray is right, you never never never ever  break your
pages that way. You won't have any SEO working accordingly. Subdomains are
used for something that is totaly away from the concept of you main domain.
So if you have a website where you sell DVDs called www.yourdvdsite.com
and then you want to create a website that sells poster of your dvds but you
don't want people to get confused at the same time you want them to know
that it is one company - one concept but 2 different products - then you use
subdomains.  With this case SEO reads 2 different area the posters and the
dvds each one in its own.
So imagine if you have subdomains of about.site.com and
products.site.com you will definitely loose ranking and everything
that helps on SEO.
Thank you guys for all the input.
Summary and Conclusion:
Your website URL is http://www.site.com
if you want your other main pages' URLs showing in a clean manner in the
address bar, just create a folder in you Root folder and call it whatever
you want (for example: products or about or contact)
Then inside of this folder, create a new html page and call it index.html
Now in the other pages, if you want to link to that new page, the link will
be ../about/ (DON'T LINK DIRECTLY TO THE index.html)
so in the address bar, you will see http://www.site.com/about/
If you link directly to the index.html the URL will show
http://www.site.com/about/index.html
And you really don't want your savvy visitors to see that do you?
HOME PAGE ISSUE:
Now in you other pages, you definitely have a link to the home page, of
course your home page is seating in the Root folder and it's called
index.html.  YES, when you click the URL will show:
http://www.site.com/index.html
Try 2 methods, if you site is still in your local drive, replace the link
"that is linking to the home page index.html" as       ../          yes 2
dots and a forward slash (this works for me on CS4.
or just type in your site's URL (in this example http://www.site.com/)
