    Default Modifying a few bytes in a large file - stupid question.

    Hi All

    This seems a bit of a silly question, but this is something I've never had to do before.
    I'm looking for a way to modify a few bytes (< 10). Spread out across a large file (>200MB).

    Is there any simple way to do this without pumping a FileInputStream to a FileOutputStream and modifying the apropriate bytes as they come through?

    Regards

    Please use [CODE] tags and indent correctly. It really helps when reading your code.
