We can use LifeCycleConfiguration to do it.

      Prefix: "transit" // The name of the folder from which the files need to be deleted.

Implementation project

This project shows the following use cases.

1. Generating and using presigned urls to put files on S3
2. Uploading files to S3
3. Zipping and Unzipping files on S3 (This happens without having to story any files on the disk)
4. Picking text files from a given S3 directory
