Explain Empty Catch

class Logbook {

    static final Path LOG_FOLDER = Paths.get("/var/log");
    static final String FILE_FILTER = "*.log";

    List<Path> getLogs() throws IOException {
        List<Path> result = new ArrayList<>();

        try (DirectoryStream<Path> directoryStream =
                     Files.newDirectoryStream(LOG_FOLDER, FILE_FILTER)) {
            for (Path logFile : directoryStream) {
                result.add(logFile);
            }
        } catch (NotDirectoryException e) {

        }

        return result;
    }
}
