Actually, there is no such limitation. The application uses a circular buffer for storing captured packets. By default, the buffer can contain up to 5,000 latest packets, but this value can be adjusted in the Settings window. The maximum buffer size is 20,000 packets (the buffer cannot be unlimited for an obvious reason: your computer's RAM is not unlimited). You can save the contents of the buffer to a file using the Logging tab. However, by no means does this limit on the buffer size restrict your ability to save any number of packets. You simply need to enable automatic logging on the Logging tab. Such automatic logging will make the application dump all the captured packets to file(s) continuously, and you can set any limit on the total size of the captured data.
