    // In this example, assume that a previous FTP upload failed,

    // the upload.  When RestartNext is set, the next call
    // to PutFile (or PutFileFromBinaryData, PutFileFromTextData)
    // will automatically resume the upload from the point of failure.
    // (The way it works is that the FTP component sends a "SIZE"
    // command to the FTP server to find out how many bytes of
    // the file already exist on the server.  It then begins
    // uploading from that point.

    // is automatically set to false.
