The whole system
is composed of two main applications: CardZort, which is
responsible for the creation of the index cards and the execution
of the sorting exercises, and CardCluster, which is responsible
for the cluster analysis of the groupings.

of the system
Every time a card
sorting exercise is finished (e.g. a subject finished grouping the
cards), CardZort generates a text file (".cz" extension).
This file contains a text-based representation of the groupings
obtained from the exercise. CardZort generates a separate ".cz"
file for each exercise completed.
Once the card sorting
exercises are completed, the next step is to analyze the groupings
given by the different subjects (remember that the grouping information
is stored in the ".cz" files generated from CardZort).
