Re: [basex-talk] problems using Archive module with certain zip files

Hi Vincent,

archive:extract-to() or archive:entries() produce this error message “Operation failed: only DEFLATED entries can have EXT descriptor.”

This error seems to be caused by to a bug in the JDK [1]. As the bug entry has been opened in 2015, I’m not sure if we can count on a quick fix.

2. When attempting to create a zip file larger than about 2 Gb.

This is a known restriction indeed. The best option might be to directly stream archives to the specified file on disk. If enough people are interested in such an extension, we could try to realize this as sponsored feature.

Best, Christian
