Hi,

Thanks for the details.

Please note, however, that DIZipWriter does not yet support the ZIP64 format so file sizes are limited to 4 GB.

That was going to be my next question, as I just noticed that the product page makes no mention of the zip64 format.

Given what I've seen re the requirement to pass the CRC32 of the 'file' to the zip writer before compressing and encrypting a 'file', I would guess that it's impossible to also encrypt a stream that's passed block my block, as happens in my case. Is that true? Does that requirement also apply to encrypting streams in the zip64 format?

Thanks.
