Delete unused files / images from asp.net project
<p>My question is somewhat different. 
Currently I am working on asp.net web project in which I have many images and html pages, out of which i am using very few. Now want to delete unused  out of them but need to check every aspx/htm/master page whether i used them or not. So is there any way i come to know that which files are unused ? Is there any tool for it ? or any thing i come to know while build/compile project ?
Thanks in advance.</p>
