Reviewing the Eclipse installation directory structure
Progress Developer Studio for OpenEdge provides a common location to install an instance of the Eclipse framework for all Eclipse-based Progress products. This eliminates the overhead of installing separate instances of the Eclipse framework for each Eclipse-based product. The default PATH for the Eclipse framework and Progress Eclipse-based products is C:\Progress\OpenEdge\oeide\eclipse.
Eclispse folder contains files which support the Eclipse framework and Progress Eclipse-based products.
