Log in to the Amazon S3 Console using your AWS account credentials.

If you haven’t already created a bucket, create a new bucket by clicking on the “Create bucket” button. Give a unique name to your bucket and select the region where you want to create the bucket. Click on the “Create” button to create the bucket.

Step 3: Select the Bucket

Select the bucket where you want to create the folder.

Step 4: Click on “Create Folder”

Click on the “Create Folder” button to create a new folder in the selected bucket.

Step 5: Name the Folder

Name the folder as per your requirement. The folder name must end with a forward slash (/) to indicate that it is a folder and not an object.

Step 6: Click on the “Create” Button

Click on the “Create” button to create the folder in the selected bucket.

Step 7: Verify the Folder

Verify that the folder has been created successfully by checking the list of objects in the bucket. The folder will be displayed with a folder icon.

Using AWS CLI to Add a Folder in Amazon S3 Bucket

Amazon S3 also provides a command-line interface (CLI) that allows you to manage your S3 resources from the command line. Here are the steps to add a folder in Amazon S3 bucket using AWS CLI:

Step 1: Install and Configure AWS CLI

Install AWS CLI on your local machine and configure it with your AWS account credentials.

Step 2: Create a Bucket

Create a new bucket using the following command:

aws s3 mb s3://bucket-name

Replace “bucket-name” with the name of your bucket.

Output:

make_bucket: bucket-name

Step 3: Create a Folder

Create a folder in the bucket using the following command:

aws s3api put-object --bucket bucket-name --key folder-name/ --content-length 0

Replace “bucket-name” with the name of your bucket and “folder-name” with the name of your folder.

Output:

{
    "ETag": "\"d41d8cd98f00b204e9800998ecf8427e\"",
    "ServerSideEncryption": "AES256"
}

Step 4: Verify the Folder

Verify that the folder has been created successfully using the following command:

aws s3 ls s3://bucket-name/folder-name/

Replace “bucket-name” with the name of your bucket and “folder-name” with the name of your folder.

Common Errors and Solutions

Error 1: Access Denied

Error Message: An error occurred (AccessDenied) when calling the PutObject operation: Access Denied

Solution: Ensure your AWS credentials have the necessary permissions to perform the S3 operations. Check IAM policies and verify that the correct access keys are used.

Error 2: NoSuchBucket

Solution: Double-check and update the AWS access key if it’s incorrect or outdated.

Error 4: BucketAlreadyExists

Error Message: An error occurred (BucketAlreadyExists) when calling the CreateBucket operation: The requested bucket name is not available. The bucket namespace is shared by all users of the system

Solution: Choose a unique bucket name that hasn’t been used by other AWS users.
