Can you explain the following? I don't see why TreeItems need to be
expanded in order for getItems() to return something useful.

// the following line only works if viewer.getTree().getItems()[0] is
expanded
TreeItem[] testing = viewer.getTree().getItems()[0].getItems();
viewer.setContentProvider(new ViewContentProvider(file));
// if I do viewer.expandAll(); here then below works fine, but not if I use
viewer.expandToLevel(Object, int)
testing = viewer.getTree().getItems()[0].getItems();

They don't. Perhaps this is a bug/feature in JFace? Try eclipse.platform.
Someone may be able to help you there.
