Note from the kdeapps maintainer:

This directory used to contain several example fax files. Some of which are
raw fax files others tiff fax files. Since I need to keep the kdeapps
distributions small in size, I removed them with the permission of the author. 
You will still find all example files in the original kfax distribution
