Java nio provides us the option to create sparse files

    val path = Path("""E:a""")

    val fileChannel = FileChannel.open(
        path,
        StandardOpenOption.READ,
        StandardOpenOption.WRITE,
        StandardOpenOption.CREATE_NEW,
        StandardOpenOption.SPARSE,
    )

The documentation says sparse file will be created if the OS and filesystem support it, but if it doesn’t it will create a regular file

But I want to know if the OS+filesystem does or does not support SPARSE so that, I can disable a feature from my app.
