For your information : My selection has all empty folders

This issue is because zip archive does not generate file if there is nothing added. I've added support for empty folders for the ZipArchive compressor, options "raw" and "native" don't yet have this as I'm not sure how to do it with them.

Fixed in 2.5.19
