Uploading an Object
This is the User Guide for the old Amazon S3 console. If you are looking for the User Guide for the new Amazon S3 console, see Welcome to the New Amazon S3 Console User Guide.
If you upload an object with a key name that already exists in the bucket, Amazon S3 creates another version of the object instead of replacing the existing object. For more information about uploading an object, see Uploading Objects into Amazon S3.
