In general, the path to your site will be: d:\inetpub\wwwroot\(your domain name)\wwwroot.
You can also determine the absolute path of the template you are running if you put the following code in your CFM template:
<cfoutput>#expandPath('.')#</cfoutput>
Remember, this code needs to be in a file with a .cfm extension and viewed through your web browser to see the path to your current file.
