 * Hi,
 * I was wondering if enabling the CDN support will both add and delete files from
   Amazon S3 and CDN? Or only add files?
 * The concern is with possible deletion.
 * Let’s say we are testing a copy of WordPress, and enable the CDN feature, and
   it notices image or upload files are missing on the local server, it might go
   and delete corresponding files on Amazon.
 * Or, a different case, if the test copy of WordPress has different files from 
   production, it will upload the test files and overwrite prod.
 * well, those are two different scenarios. In any case, feedback is appreciated.
   thanks.
