    Hi

    Enhanced Deflate was in PKZIP 2.04g, referred to "Deflate64 format" by UNZIP

    Cheers

    I don't foresee that happening, for several reasons:

    1) It isn't supported in the compression library we're using.

    2) It's considered proprietary by PKWare (and is not documented).

    3) It only provides a trivial improvement in compression. I don't see any
    other advantage to the format (and it has pretty much disappeared from the
    archiving scene).
