How to download a S3 File From S3bucket and store a Shared folder

Filepath is your shared folder path where you want to download and then you can return the full path as "/shared/Filename" as transferutility.download returns void .

TransferUtility fileTransferUtility =
new TransferUtility(
new AmazonS3Client("ACCESS-KEY-ID", "SECRET-ACCESS-KEY", Amazon.RegionEndpoint.CACentral1));
// Note the 'fileName' is the 'key' of the object in S3 (which is usually just the file name in your case image name)
fileTransferUtility.Download(filePath, "my-bucket-name", fileName);
