Description

I am trying to extract NetFlow statistics from a list of pcap files. The file has been formatted as follows:

/path/to/pcap/file1.pcap
/path/to/pcap/file2.pcap 
/path/to/pcap/file3.pcap 

and is passed as an argument to nprobe in this way:
nprobe.exe /c --pcap-file-list "C:\Users\user\nprobe\pcap.list" -V 10 -n none -T "%FIRST_SWITCHED%LAST_SWITCHED%IPV4_SRC_ADDR%L4_SRC_PORT%IPV4_DST_ADDR%L4_DST_PORT%PROTOCOL%L7_PROTO%IN_BYTES%IN_PKTS%OUT_BYTES%OUT_PKTS%TCP_FLAGS%FLOW_DURATION_MILLISECONDS%SRC_TO_DST_AVG_THROUGHPUT%DST_TO_SRC_AVG_THROUGHPUT" --dump-format t --csv-separator ";"
However, the statistics are calculated from the packets captured on the WiFi interface and not from the pcap files.

Research direction

Start with the nProbe command invocation and the --pcap-file-list option shown in the issue, then trace how the input source is selected. Reproduce the command using the listed PCAP paths and verify that the resulting NetFlow statistics come from those files rather than the WiFi interface.
