If you upload individual files and you have a folder open in the Amazon S3 console, when Amazon S3 uploads the files, it includes the name of the open folder as the prefix of the key names. For example, if you have a folder named backup open in the Amazon S3 console and you upload a file named sample1.jpg, the key name is backup/sample1.jpg. You’ll need to delete the old file and upload a new one instead. Amazon have also done a great job at providing SDKs for a range of platforms, like.NET, Java, Python etc. Programmatic access to S3’s services is equally available. As with many other Amazon components don’t assume that S3 can only be used with other Amazon components. The Scenario¶.
