Bug 102285 [Import/Export] Project Import wizard unusably slow
R3.1 I wanted to create a new 3.2 workspace and import some projects from my 3.1 development workspace which contains around 120 plug-ins. I've set the root of the importer to point at those plug-ins. After letting the wizard scan my disk for over 10 minutes I gave up and did it manually. A possible source for the problem might be that the root directory (as expected) contains a .metadata directory with tons of data (in my case) and that this one is fully scanned.

		if (fileName.length() == 0)
			fileName = previouslyBrowsedArchive;
		if (fileName.length() == 0)
			dialog.setFilterPath(IDEWorkbenchPlugin.getPluginWorkspace()
					.getRoot().getLocation().toOSString());
		else {
			File path = new File(fileName);
			if (path.exists())
				dialog.setFilterPath(new Path(fileName).toOSString());
		}
		String selectedArchive = dialog.open();
		if (selectedArchive != null) {
			previouslyBrowsedArchive = selectedArchive;
			archivePathField.setText(previouslyBrowsedArchive);
			updateProjectsList(selectedArchive);
		}
