S3 Browser allows you to use buckets and folders shared by another Amazon S3 users.

You need three things to use shared Amazon S3 Bucket:

• Access Key ID
• Secret Access Key
• Bucket name (and optionally a folder name)

If you have an Amazon S3 or AWS Account, you can find your Access Key ID and Secret Access Key using the following link: https://aws-portal.amazon.com/gp/aws/developer/account?ie=UTF8&action=access-key

If you don't have an AWS Account, the person who want to share the bucket with you, can create an IAM Account for you and provide Access Key ID, Secret Access Key and Bucket/Folder name. Above you may find detailed instructions on how to create new IAM user and share the bucket/folder with them.

Ok, let's assume that you have the keys and bucket name. Now you need to download and install S3 Browser and enter your Access Key ID and Secret Access Key.

Then click Buckets->Add External Bucket

Click Buckets->Add External Bucket.
