Hello,

What is a "default directory"?

You should place your website's content in the root of the website. By
default, this is C:\Inetpub\wwwroot\.

You can name the default page anything you like, as long as it is listed
in the "Default Documents list". To alter this list:

Open IIS Manager
Right click the website and click properties.
Click on the Documents tab.
Add the name of the file to the list, and move it to the top.

I dont understand "My website is called MyWebSites". Is that the name of
the pc? Is it the description (like "Default Web Site")?

What do you mean by command line? Do you mean the URL/address? If so, you
should use this:

http://serverName/index.htm

Where serverName is replaced by the name of your server, or the IP.

Hope this answers all your questions. If not, or you need more help,
please tell us!

Good Luck!
