TCP stream reassembly combines those payload-bearing segments into the file; the FTP control messages in frames 7 and 21 contain only the resume command and completion status. **Learn more:** [Wireshark User's Guide — Following TCP Streams](https://www.wireshark.org/docs/wsug_html_chunked/ChAdvFollowStreamSection.html)
