How to Rename an AWS S3 File: A Comprehensive Guide

Renaming a file in AWS S3 is a straightforward process, involving copying the file to a new name and then deleting the original file. Since AWS S3 does not support traditional file operations like renaming within the S3 interface, we need to follow these steps to achieve this.

Renaming a File in AWS S3

Note: It’s important to understand that renaming an S3 bucket is not possible. If you need to change the bucket name, you’ll need to create a new bucket and then move the objects from the old bucket to the new one. This process can be managed using the AWS CLI or the AWS Management Console.

Using the AWS Management Console

The following steps guide you through renaming a file in S3 using the AWS Management Console:

Log in to the AWS Management Console: Navigate to S3 and open the bucket containing the file. Select the file you want to rename. Click on the “Actions” button and select “Copy”. In the dialog that appears, specify the new name and optionally a new path for the file. Click “Copy” to create the new file. Once the copy is complete, go back to the original file, select it, and click on “Actions”. Then choose “Delete” to remove the original file.

Using the AWS CLI

The AWS Command Line Interface (CLI) also allows you to rename a file using some simple commands:

Copy the file to the new name

aws s3 cp s3://your-bucket/old-file-name s3://your-bucket/new-file-name

Delete the original file

aws s3 rm s3://your-bucket/old-file-name

Using SDKs e.g. Boto3 for Python

For those using an SDK like Boto3, the process is as follows:

import boto3
s3  ('s3')
bucket_name  'your-bucket'
old_file_name  'old-file-name'
new_file_name  'new-file-name'
# Copy the file
_object(
    Bucketbucket_name,
    CopySourcef'{bucket_name}/{old_file_name}',
    Keynew_file_name
)
# Delete the old file
_object(
    Bucketbucket_name,
    Keyold_file_name
)

Summary

To rename a file in S3, copy it to a new name and then delete the original file. Always ensure you have the necessary permissions to perform these actions in your S3 bucket.
