How to check a file is shortcut file?

Question

Following code fails to check the shortcut file. code source Suppose there is file sdcard/1234567.mp3 which is not shortcut file even the absolute and canonical paths are different.

public static boolean isShortcutFile(File file) {
        try {
            if (!file.exists()) {
                return true;
            } else {
                return !file.getAbsolutePath().equals(file.getCanonicalPath());
            }
        } catch (IOException ex) {
            System.err.println(ex);
            return true;
        }
    }

Alternate way what i tried is checking the extension of a file is .lnk will it work for all case?
