Where are the outfile_000&&_20130222&&&&&&.pcap saved

I just don't seem to find them.

Accepted Answer

I would guess nowhere. From the prompt, you're running the capture from within the Wireshark "Program Files" directory and a normal user account doesn't have write permission in that directory so the files aren't written.

Either run the command from within a directory to which you do have write permission, or change the output file parameter to include a path that you can write to, e.g. c:\temp\outfile.pcap
