你在这里因为你有，有一个文件扩展名结尾的​​文件 .pcap. 文件与文件扩展名 .pcap 只能通过特定的应用程序推出。这有可能是 .pcap 文件是数据文件，而不是文件或媒体，这意味着他们并不是在所有观看。

什么是一&nbsp.pcap&nbsp文件？

该.pcap文件扩展名主要使用Wireshark相关;用于分析网络的程序。 .pcap文件是使用程序创建的数据文件，并且它们包含的网络的分组数据。这些文件主要用于分析的特定数据的网络特性。这些文件也有助于成功地控制在一定的网络流量，因为它们是由该程序监测。数据和网络分析的结果使用保存.pcap文件扩展这就是为什么它们被称为.pcap文件。这些文件被用于确定网络状态，使得分析仪参加到可能发生在网络上，并允许它们是研究用Wireshark的数据通信的问题。由于Wireshark的可以在Windows，Mac和Linux进行访问，这些.pcap也可以打开的文件提供用于打开它们相应的应用程序被发现在系统上。可以打开一些常用的应用程序.pcap文件是Wireshark的，WinDump的，tcpdump的，包广场- Capedit和空灵。

如何打开 .pcap 文件？

推出 .pcap 文件，或者你的电脑上的任何其他文件，双击它。如果你的文件关联的设置是否正确，这意味着应用程序来打开你的 .pcap 文件将其打开。这是可能的，你可能需要下载或购买正确的应用程序。这也有可能是你有正确的应用程序在PC上，但 .pcap 文件还没有与它相关联。在这种情况下，当您尝试打开一个 .pcap 文件，你可以告诉Windows的应用程序是正确的该文件。从这时起，打开 .pcap 文件将打开正确的应用程序。 点击这里修复.pcap文件关联错误

Wireshark

Wireshark

Wireshark is an application that is integrated with features for monitoring relevant network activity and for storing these pieces of data into logs and databases for future analysis. This software is classified as a network management and data analysis program, and this application was developed for network computers that are running on compatible Windows-based systems. Different network protocols can be monitored, tracked and analyzed by Wireshark, providing network system administrators and IT personnel with a quick and easy way to improve the efficiency of network ports and data transmissions to and from network computers, other devices that are connected to the network and Internet servers. Version 1.8.5 is the most recent stable release of Wireshark, which was developed by Riverbed Technologies. This version is now implemented with support for computers that are running on Mac OS X 10.5.5. The Wireshark source code is also available for developers who intend to add plugins and add other useful functionalities to the integrated features of this network analysis program.

Netresec NetworkMiner

Netresec NetworkMiner

Netresec NetworkMiner is an application that is classified as a network forensics analysis program, and this software is implemented with compatibility support for Windows-based computers. The latest version of this application is also embedded with support for other types of operating systems, such as Linux, BSD and Mac platforms. NetworkMiner is integrated with features that can allow users to determine network-relevant information like system types and versions of computers that are connected to the network or are trying to access resources of the network, along with the IP addresses of those machines, open ports, hostnames and active session logs among others. There are also other packet capturing and passive sniffing functionalities that are integrated into Netresec NetworkMiner, and these can be used by system administrators and IT personnel to secure the network and optimize the efficiency of protectitive and privacy-related resources that are available to all computers and devices which have been granted access to the network. PCAP file parsing features are available in this software, along with the function of reassembling or regenerating certificates and files that have already been transmitted to and from network devices. Netresec NetworkMiner was designed to gather forensic network details and not network traffic data.

WinDump

WinDump

WinDump is an application that is categorized as a network analysis program, and this software was developed for computers that are running on compatible versions of widely used Windows systems. WinDump is integrated with a command line user interface and many features that allow users to gather network-related data and store it in logs for future analysis, via the Windows command line. WinDump was created to serve as the Windows version of the tcpdump application, which is implemented with support for UNIX-based platforms. Network packet capturing functionalities are integrated into this application, and this network analysis software was developed by Riverbed Technologies, a popular software development group that also created Wireshark. Network system administrators and IT personnel of businesses and companies can use WinDump to closely monitor and store logged details of network activity, which can later be used for improving certain settings of the network infrastructure that can in turn enhance the efficiency of data transmissions to and from computers and devices connected to the network, and these details can also help system administrators in fortifying network security.

提醒一句

要小心，不要重命名扩展&nbsp.pcap&nbsp文件，或任何其他文件。这不会更改文件类型。只有特殊的转换软件可以从一个文件类型更改一个文件到另一个。

什么是文件扩展名？

文件扩展名是一组三个或四个字符在文件名的末尾，在这种情况下，&nbsp.pcap.&nbsp文件扩展名告诉你它是什么类型的文件，并告诉Windows哪些程序可以打开它。窗户经常关联一个默认程序的每个文件的扩展名，这样，当你双击该文件，程序会自动启动。当该程序不再是您的PC上，有时可以得到一个错误，当您试图打开相关的文件。
