What is a pcap file and how do I open a pcap file?
The .pcap file extension is mainly associated with Wireshark; a program used for analyzing networks. .pcap files are data files created using the program and they contain the packet data of a network. These files are mainly used in analyzing the network characteristics of a certain data. These files also contribute to successfully controlling traffic of a certain network since they are being monitored by the program. The data and the results of the network analysis are saved using the .pcap file extension which is why they are called .pcap files. These files are used to determine network status, allowing analyzers to attend to problems that may have occurred on the network and allowing them to study data communications using Wireshark. Since Wireshark can be accessed in Windows, MAC and Linux, these .pcap files can also be opened provided the appropriate applications used to open them are found on the system. Some common applications that can open .pcap files are Wireshark, WinDump, tcpdump, Packet Square - Capedit and Ethereal.
