The Oberon system V4 supports hierarchical directories, but it has no easy way to work with them. In this paper we present the development of a comfortable file browser tool based on Oberon text elements. Implementation aspects, such as advanced object-oriented and message-driven programming techniques and some interesting workarounds for problems with incompatibilities of different Oberon systems on various hardware platforms are discussed.

Keywords: GUI, Object-oriented Programming, Reusability of Software Components, Text Elements, Message Handling, Oberon System.
