Values.S3InputFileLocationSourceSpecifies the customer input Amazon S3 file location. If it is used inside copyStepDetails.DestinationFileLocation, it should be the S3 copy destination. You need to provide the bucket and key. The key can represent either a path or a file. This is determined by whether or not you end the key value with the forward slash (/) character. If the final character is "/", then your file is copied to the folder, and its name does not change. If, rather, the final character is alphanumeric, your uploaded file is renamed to the path value. In this case, if a file with that name already exists, it is overwritten. For example, if your path is shared-files/bob/, your uploaded files are copied to the shared-files/bob/, folder. If your path is shared-files/today, each uploaded file is copied to the shared-files folder and named today: each upload overwrites the previous version of the bob file.
