Amazon S3 multipart upload limits

Multipart upload allows you to upload a single object as a set of parts. Each part is a contiguous portion of the object's data. After all parts of your object are uploaded, Amazon S3 assembles these parts and creates the object. In general, when your object size reaches 100 MB, you should consider using multipart uploads instead of uploading the object in a single operation. For more information about multipart uploads, see Uploading and copying objects using multipart upload.
