Bug 312540 [LinkedResources] Copy resource in Navigator and Project Explorer always shows dialog
N20100511-2000. When copying an IFile from one to another folder in the Navigator or Project Explorer, I always get the dialog no matter how I've set the preferences on the 'Linked Resources' page (even if I disable linked resources).
bundles/org.eclipse.ui.navigator.resources/src/org/eclipse/ui/navigator/resources/ResourceDropAdapterAssistant.java
IContainer target = getActualTarget((IResource) dropAdapter.getCurrentTarget());
		boolean shouldLinkAutomatically = false;
		if (target.isVirtual()) {
			shouldLinkAutomatically = true;
			for (int i = 0; i < sources.length; i++) {
				if ((sources[i].getType() != IResource.FILE) && (sources[i].getLocation() != null)) {
					
					
					
					shouldLinkAutomatically = false;
					break;
				}
			}
		}
		CopyFilesAndFoldersOperation operation = new CopyFilesAndFoldersOperation(shell);
		
		
		if (shouldLinkAutomatically) {
			operation.setCreateLinks(true);
			operation.copyResources(sources, target);
		} else {
			boolean allSourceAreLinksOrVirtualFolders = true;
			for (int i = 0; i < sources.length; i++) {
				if (!sources[i].isVirtual() && !sources[i].isLinked()) {
					allSourceAreLinksOrVirtualFolders = false;
					break;
				}
			}
