Provides a high level utility for managing transfers to and from Amazon S3.
TransferUtility provides a simple API for uploading content to and downloading content from Amazon S3. It makes extensive use of Amazon S3 multipart uploads to achieve enhanced throughput, performance, and reliability.
When uploading large files by specifying file paths instead of a stream, TransferUtility uses multiple threads to upload multiple parts of a single upload at once. When dealing with large content sizes and high bandwidth, this can increase throughput significantly.

| Dispose()()()() |
Disposes of resources and initiates garbage collection
for the TransferUtility class.
|
| Download(TransferUtilityDownloadRequest) |
Downloads the content from Amazon S3 and writes it to the specified file.
If the key is not specified in the request parameter,
the file name will used as the key name.

| Upload(TransferUtilityUploadRequest) |
Uploads the file or stream specified by the request.
To track the progress of the upload,
add an event listener to the request's UploadProgressEvent.
For large uploads, the file will be divided and uploaded in parts using
Amazon S3's multipart API. The parts will be reassembled as one object in
Amazon S3.
|
| Upload(String, String) |
Uploads the specified file.
The object key is derived from the file's name.
Multiple threads are used to read the file and perform multiple uploads in parallel.

Amazon S3's multipart API. The parts will be reassembled as one object in
Amazon S3.
|
| Upload(Stream, String, String) |

Remarks
Transfers are stored in memory. If the application is restarted, previous transfers are no longer accessible. In this situation, if necessary, you should clean up any multipart uploads that are incomplete.
