SFTP TCP conversation question

When a client initiates an SFTP upload to a server - is the size of the file to be coming included in the early part of the conversation? It would be helpful to know in some instances. Thank you.

The answer is no. I mean on the protocol layer, it will not send the file size to server before start uploading. Instead, it upload file chunk by chunk, each chunk has an offset and length. If the server doesn't have enough space to save the data, an error will be returned to client which should be handled properly.  Seeing reference here: https://tools.ietf.org/html/draft-ietf-secsh-filexfer-13
