In this paper, we use a cognitive walkthrough as well as a laboratory user study to analyze the usability of the Kazaa file sharing user interface. We discover that the majority of the users in our study were unable to tell what files they were sharing, and sometimes incorrectly assumed they
were not sharing any files when in fact they were sharing all files on their hard drive. We also looked at the current Kazaa network, and determined that a large number of users are currently sharing personal and private files without their knowledge, and from our dummy server we were able to see that other users are indeed taking advantage of this and downloading files such as "Credit Cards.xls" and email files.
