The Reduced Zip library (Ionic.Zip.Reduced.dll) differs from the \"normal\" zip library (Ionic.Zip.dll) in exactly one way: the reduced form does not include the ability to create self-extracting archives. If you are not creating a self-extracting archive, then there is absolutely no difference between the regular library and the reduced version. Because of that, the idea that the reduced version somehow \"fixes\" the problem that Pashute saw with zip files on the Mac, is suspect. After all the back and forth, I still don't understand the root cause of the problems he saw on the Mac. I didn't put anything in v1.9.0.30 to fix any problem reported here. Using the reduced library will not make any difference, in any problem not related to self-extracting archives. In general, Zip files generated by DotNetZip will open successfully on the Mac. If you have problems with Zip files generated by DotNetZip opening on the Mac, then please open a new discussion on the forums. http://dotnetzip.codeplex.com/Thread/List.aspx . I'll be happy to work through it with you. \r\n", "PostedDate": "2009-11-19T09:22:27.467-08:00", "Id": -2147483648 }, { "Message": "", "PostedDate": "2009-11-19T09:23:01.98-08:00", "Id": -2147483648 }, { "Message": "", "PostedDate": "2013-02-21T18:43:58.737-08:00", "Id": -2147483648 }, { "Message": "", "PostedDate": "2013-05-16T05:32:06.153-07:00", "Id": -2147483648 } ] }
