To provide GET flexibility, Amazon S3 supports chunked and resumable downloads.
This allows you to download part of an object stored in Amazon S3 so you can break
large downloads into smaller chunks or design your applications to recover from failed downloads.
You can select a method from the following:
For information about using resumable downloads with the REST API, go to
RESTObjectGET.
For information about using resumable downloads with the SOAP API, go to
