C++ Winsock Datei Senden

einen Einfachen Server und Client, ich kann eine Datei senden,
Und ich brauche Euch Jungs zu sehen, wenn diese Quelle fertig sind.
Cuz ich denke, es wird nicht download der kompletten Datei.

Und vielleicht, um diese Quelle eine Grenze haben ? Cuz, das ich hochgeladen/heruntergeladen 200K und ein bisschen mehr ..
