File size too big even after using port not 8080 filter

In milestone 3 of module 5 even after using filters (port not 8080, -n tcp), I just cant reduce the file size. Its always more than 10 MB. @Kiran could you help me out? Thanks

When you try to capture packets into pcap file, you can first connect the QBox server and filezilla . After successful connection, you can just start capturing packets and transfer a small file and stop capturing packets. And can proceed the tasks mentioned in the milestone.
