Wireshark and File Compression

A Wireshark feature I like to use is the built-in file compression option. This comes in handy for emailing or storing huge trace files. Wireshark will compress and decompress the file without a third-party compression tool, which is very convenient.

After using the gzip feature for a while, I had a client ask a great question: “Is Wireshark more efficient than manually 'zipping' the trace file?” Sounds like a challenge to me.

In this video, I compare Wireshark’s gzip capability and the popular 7-Zip free compression utility.
