I used QuarterDeck Zipit, and it says there are more files than that. Specifically, the compressed file contains:

PongCache.jar
LimeWire.props
gnutella.net
startup.sh
readme.txt
Simple Pong Cache-directory-

So, if you only got 2 files, I find that slightly odd. Don't you?

I am guessing you are using a file browser rather than a terminal using the ls command. Check and see if the file types are hidden by your file browser. I know Konqueror hides files by default (on Mandrake 8.0).
