When you add a connectivity bundle or an adapter bundle to a project in the Project Explorer view, the bundle appears in the project's directory structure. Many bundles contain only EPL or Java files. Adding these bundles means that references to the bundle files will be added to the project build path, but does not involve copying any files into the project. However, when you add a connectivity bundle or an adapter bundle that contains customizable files such as .evt or configuration files, Software AG Designer physically copies these files into the project, in addition to the changes made to the project build path.

If you add more than one instance of a particular connectivity bundle or an adapter bundle to the project, Software AG Designer creates separate copies of these files for each instance (except for bundles where it only makes sense to have one copy of the instance files per project). You can change and customize the bundle instance files in any manner. It is possible to add multiple instances of such bundles to a given project to allow different customization of the same instance files, for example if your application needs to run with two instances of a particular adapter, each connected to a different data provider.
