S3 Download from a specific folder

I have two folders inside my s3 bucket. How can I download all the files only from only bucket_one.

This is the code I am using to download from bucket. Now I want to download from a folder inside that bucket.

GetObjectRequest request = new GetObjectRequest(BucketName(),KeyName());
       S3Object object = s3Client.getObject(request);
       S3ObjectInputStream objectContent = object.getObjectContent();
       IOUtils.copy(objectContent, new FileOutputStream(System.getProperty("user.home")+"//downloads//"+KeyName()));

Thanks

The above answer provided by Frederic Henri is correct but you should not include / if yourFolder is the last folder .i.e, if directory is <yourBucket>/<lvlOne>/<lvlTwo>/, then at the end of folder lvlTwo, you should not include \

You can list all files in the bucket of a particular folder and download them individually or you may take a loot at MultipleFileDownload interface in the TransferManager class

Just indicate the full path of the folder in question

Change your BucketName() method to be something like folderName() which will be bucketName() + "/" + <yourfolder> + "/"

the "/" is important at the end otherwise S3 will search for a file within your bucket root folder

You can use the same to go deeper in your folder structure : bucketName() + "/" + <folder1> + "/" + <folder2> + "/"
