Transforming a .pcap file to a text file on windows 7 using tshark

When i typed that, the windows 7 command line interface showed this message : tshark: "Sample.pcap" is neither a field or a protocol name. Is there a mistake in the command or there is another problem?

Is there a mistake in the command

Yes. What is the pathname of the capture file? Is C:\Users\Tok Jun Xin\Desktop\WiresharkLog\SynFlood a directory with a Sample.pcap file in it? If so, the command you want is

tshark -V -r "C:\Users\Tok Jun Xin\Desktop\WiresharkLog\SynFlood\Sample.pcap" > "C:\Users\Tok Jun Xin\Desktop\logcapture.txt"

Yeah. That is what i meant

OK, I fixed the command line in the answer to reflect the pathname of the capture file being

C:\Users\Tok Jun Xin\Desktop\WiresharkLog\SynFlood Sample.pcap

as, when looking at the original question, it looks as if the capture file name is SynFlood Sample.pcap (with a space in the name) and it's in the directory C:\Users\Tok Jun Xin\Desktop\WiresharkLog (with a space in the user name).
