This paper dsescribes a prototype tool which visualizes files attached to emails. It is a graphic representation materialized in the form of directed graph. The vertex represents a participant in the conversation and the edge embodies the email. As the files may belong to the same project, we propose to use the clustering based on the mixture approach to determin different classes. A color is associated to each class. The files of the same class are represented by different geometric shapes with degraded color. The geometric shapes are displayed on the edges.
