AMAZON WEB SERVER

I am searching my s3 bucket and I would like to know how can I check total number of objects (files) I have uploaded inside particular S3 Bucket on amazon web server? I am looking for easy solution here.

When I uploaded the new website on Amazon EC2 server using IIS, I got HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid here are the more error details were

This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".

Config Source:
   33:     <urlCompression doDynamicCompression="true" doStaticCompression="true" dynamicCompressionBeforeCache="true" />
   34:     <modules>
   35:       <remove name="FormsAuthentication" />

Here is the image of the error
