This article summarizes 5 methods for Wireshark file extraction from network traffic.
Export Packet Bytes
- Pros: One-click export, suitable for small files of a single request.
- Cons: Cannot export large files downloaded in segments.

Here I downloaded a zip file from the website.
Right-click the server’s response packet and track the HTTP stream.
Switch to raw data.
Save it as xxx.zip.

- Pros: This method can extract large files downloaded in segments.
File –> Export Objects
Stop capture before exporting
