Re: All my POI built Excel files are suddenly corrupt?

The idea is that the Zip64 mode is only needed for big files and SXSSF is f=
or big files.
XSSF could have the support added too but it hasn't been a priority. In the=
ory, we could add it to all the poi-ooxml doc types.

The ZIP file seems to be valid as I have been able to open it with any
ZIP tool and also any other Spreadsheet solution I have.

I think we need to understand first, what exactly triggers the problem.
And LibreOffice does not output much information unfortunately.
Also, I do not really understand why ZIP compression is different for
SXSSF vs. XSSF?

However, in the meantime it may be safest to
set=C2=A0Zip64Mode.AlwaysWithCompatibility=C2=A0and also to print this
recommendation somewhere on the website?

Thanks a lot and cheers!
