The better will be

root  /home/folder/www;

location / {
     index  index.php;
     fastcgi_pass   ...
     fastcgi_param  SCRIPT_FILENAME  /home/folder/www/index.php;
     include   fastcgi_params;
}

location ~* \.(html|jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js|swf)$ {
     expires 30d;
}

or

root  /home/folder/www;

location / {
     try_files   $uri  $uri/   @php;
     index  index.php;
     expires 30d;
}

location \.php$ {
     fastcgi_pass   ...
     fastcgi_param  SCRIPT_FILENAME  /home/folder/www$uri;
     include   fastcgi_params;
}

location @php {
     fastcgi_pass   ...
     fastcgi_param  SCRIPT_FILENAME  /home/folder/www/index.php;
     include   fastcgi_params;
}
