Abort Multipart Uploads to an S3 Bucket Using the AWS SDK for .NET (High-Level API)

To abort in-progress multipart uploads, use the TransferUtility class from the AWS SDK for .NET. You provide a DateTimevalue. The API then aborts all of the multipart uploads that were initiated before the specified date and time and remove the uploaded parts. An upload is considered to be in-progress after you initiate it and it completes or you abort it.

Because you are billed for all storage associated with uploaded parts, it's important that you either complete the multipart upload to finish creating the object or abort it to remove uploaded parts. For more information about Amazon S3 multipart uploads, see Multipart Upload Overview. For information about pricing, see Multipart Upload and Pricing.

The following C# example aborts all in-progress multipart uploads that were initiated on a specific bucket over a week ago. For information about the example's compatibility with a specific version of the AWS SDK for .NET and instructions on creating and testing a working sample, see Running the Amazon S3 .NET Code Examples.

You can also abort a specific multipart upload. For more information, see List Multipart Uploads to an S3 Bucket Using the AWS SDK for .NET (Low-level).
