You can remove an external resource from the Class Browser. To do this, you must be browsing by resource (rather than by project).
If an external resource was also defined by a project, the resource will still be listed in the Class Browser; however, the Remove External Resources option will be disabled.
To remove external resources:
1. In the Browser pane, select one or more external resources you want to remove.
2. Right-click, and choose Remove External Resources from the context menu. A message appears asking you to confirm the removal of the resource(s).
3. Click OK. The Class Browser view refreshes, and the external resources are no longer listed.
