NBAR will do the trick without any problem as it can inspect traffic up to layer 7.

I tested 2 PCs (1 server, 1 client with a file 200M) but FTP packets increased a few while unknown packets were counted up fast when I show ip nbar protocol-discovery, I used wireshark and it show a few FTP packets on port 21.
