pcapFS is a FUSE module allowing it to mount captured network data as a virtual file system. This makes it especially convenient to analyze the payload (and to some extend the metadata) of your captured network traffic. Instead of extracting the payload (i.e. copying the data to disk), pcapFS provides direct access into the PCAP files. To speed the access up, an index is created when a PCAP is mounted for the first time. This takes almost the same time as opening a PCAP with Wireshark. After the index is created, we can use it for all further operations. Moreover, the index can be used to mount the PCAP any time later making the data available almost instantly.
