# zip64_local_header

AESZipInfo.zip64_local_header(zip64, file_size, compress_size)

  If zip64 is required, return encoded extra block and other parameters which may alter the local file header.

  The local zip64 entry requires that, if the zip64 block is present, it must contain both file_size and compress_size. This is different to the central directory zip64 extra block which requires only fields which need the extra zip64 size be present in the extra block.
