Deleting objects from a directory bucket - Amazon Simple Storage Service

Deleting objects from a directory bucket

You can delete objects from an Amazon S3 directory bucket by using the Amazon S3 console, AWS Command Line Interface (AWS CLI), or AWS SDKs. For more information, see Working with directory buckets and S3 Express One Zone.

Warning

  • Deleting an object can't be undone.

  • This action deletes all specified objects. When deleting folders, wait for the delete action to finish before adding new objects to the folder. Otherwise, new objects might be deleted as well.

Note

When you programmatically delete multiple objects from a directory bucket, note the following:

  • Object keys in DeleteObjects requests must contain at least one non-white space character. Strings of all white space characters are not supported.

  • Object keys in DeleteObjects requests cannot contain Unicode control characters, except for newline (\n), tab (\t), and carriage return (\r).

To delete objects

  1. Sign in to the AWS Management Console and open the Amazon S3 console at https://console.aws.amazon.com/s3/.

  2. In the left navigation pane, choose Buckets.

  3. Choose the Directory buckets tab.

  4. Choose the directory bucket that contains the objects that you want to delete.

  5. Choose the Objects tab. In the Objects list, select the check box to the left of the object or objects that you want to delete.

  6. Choose Delete.

  7. On the Delete objects page, enter permanently delete in the text box.

  8. Choose Delete objects.

SDK for Java 2.x

The following example deletes objects in a directory bucket by using the AWS SDK for Java 2.x. 

static void deleteObject(S3Client s3Client, String bucketName, String objectKey) {


        
        try {
            
            DeleteObjectRequest del = DeleteObjectRequest.builder()
                    .bucket(bucketName)
                    .key(objectKey)
                    .build();

            s3Client.deleteObject(del);
            
            System.out.println("Object " + objectKey + " has been deleted");
            
            
        } catch (S3Exception e) {
            System.err.println(e.awsErrorDetails().errorMessage());
            System.exit(1);
        }
        
    }
SDK for Python

The following example deletes objects in a directory bucket by using the AWS SDK for Python (Boto3). 


import logging
import boto3
from botocore.exceptions import ClientError

def delete_objects(s3_client, bucket_name, objects):
    '''
    Delete a list of objects in a directory bucket

    :param s3_client: boto3 S3 client
    :param bucket_name: Bucket that contains objects to be deleted; for example, 'doc-example-bucket--usw2-az1--x-s3'
    :param objects: List of dictionaries that specify the key names to delete
    :return: Response output, else False
    '''

    try:
        response = s3_client.delete_objects(
            Bucket = bucket_name,
            Delete = {
                'Objects': objects
            } 
        )
        return response
    except ClientError as e:
        logging.error(e)
        return False
    

if __name__ == '__main__':
    region = 'us-west-2'
    bucket_name = 'BUCKET_NAME'
    objects = [
        {
            'Key': '0.txt'
        },
        {
            'Key': '1.txt'
        },
        {
            'Key': '2.txt'
        },
        {
            'Key': '3.txt'
        },
        {
            'Key': '4.txt'
        }
    ]
    
    s3_client = boto3.client('s3', region_name = region)
    results = delete_objects(s3_client, bucket_name, objects)
    if results is not None:
        if 'Deleted' in results:
            print (f'Deleted {len(results["Deleted"])} objects from {bucket_name}')
        if 'Errors' in results:
            print (f'Failed to delete {len(results["Errors"])} objects from {bucket_name}')

The following delete-object example command shows how you can use the AWS CLI to delete an object from a directory bucket. To run this command, replace the user input placeholders with your own information.

aws s3api delete-object --bucket bucket-base-name--zone-id--x-s3 --key KEY_NAME

For more information, see delete-object in the AWS CLI Command Reference.

The following delete-objects example command shows how you can use the AWS CLI to delete objects from a directory bucket. To run this command, replace the user input placeholders with your own information.

The delete.json file is as follows: 


{
    "Objects": [
        {
            "Key": "0.txt"
        },
        {
            "Key": "1.txt"
        },
        {
            "Key": "2.txt"
        },
        {
            "Key": "3.txt"
        }
    ]
}

The delete-objects example command is as follows:

aws s3api delete-objects --bucket bucket-base-name--zone-id--x-s3 --delete file://delete.json

For more information, see delete-objects in the AWS CLI Command Reference.
