Enabling the “Allow subdissector to reassemble TCP streams” feature in Wireshark allows the tool to reassemble TCP segments into a contiguous sequence, which can be used by higher-level protocols to reconstruct a full message, such as an HTTP request or response. This is particularly useful for extracting files or data transmitted over TCP that are spread across multiple packets1.
