how do I know what web.config file is being used

Greetings-
     I inherited a mess.  I have a broken website and I am looking at it in IIS7.  I cannot tell what web.config file is being used.  There are 15 of them in the directory.  I just don't know where to look.  Any direction would be great!

Thanks!

Open project and open web.config and try saving it as (but dont save as actually), it will take you to the folder where it is located.

2nd way is to rename web.config files one by one if you can afford some down time :-)

there will be only one file with the name as web.config and rest all can be gracefully ignored

Actually, there is a hierarchy of config files. Those which are below your web site's file override the ones above when a browser points there. See http://www.freewebdevelopersite.com/2011/04/17/asp-net-4-0-configuration-hierarchy-machine-config-and-web-config-inheritance/

Thank you all for the replies...  I learned so much.  I guess I should qualify my question.  How do I find out where it tells the site to use web2.config.  I found that the system is using that one via khalidmehmoodawan suggestion of renaming the files.  It was a tedious process and there has to be a way to tell the site to use that specific file.  I just dont know where.

Cheers!
