A user executes a shell script to split a large file (typically 100 MB or greater) into multiple part files. Then the script initiates the multipart upload and uploads each part file one by one. Once the part files upoload is complte the script completes the multipart upload by merging the part files into the original file.
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. You can upload these object parts independently and in any order. If transmission of any part fails, you can retransmit that part without affecting other parts. 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.
