When I use:</p>\n<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; using (ZipFile zip = new ZipFile())<br /> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {<br /> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; string[] files = Directory.GetFiles(@\"MyDocuments\\ProjectX\");<br /> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // add all those files to the ProjectX folder in the zip file<br /> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; zip.AddFiles(files, \"ProjectX\");<br /> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; zip.Comment = \"This zip was created at \" + System.DateTime.Now.ToString(\"G\");<br /> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; zip.MaxOutputSegmentSize = 4 * 1024 * 1024 * 1024;&nbsp;&nbsp; // 4Gb<br /> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; zip.Save(\"ProjextX.zip\");<br /> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }</p>\n<p>than MaxOutputSegmentSize is obviously flowing over. But I've seen somewhere else that it is possible to write larger files on a 64Bit OS (with Ionic zip). Please give a sample for that and let me what useful limits there are?</p>\n<p>&nbsp;</p>\n<p>Thanks a lot</p>\n<p>Ps.: I'd like to give the end-user a choice of whether he wants to use a 3, 3.5, or 4Gb (variable) span size. Is it possible to define this beyond 2Gb? Under 2Gb everything's working smoothly with the above code...</p>",

Can you specify more precisely what these limits are? I expected to be able to choose a spanning size between a few Mb and whatever the maximum spanning size happens to be (say 4Gb).</p>\r\n<p>&nbsp;</p>\r\n<p>In this post there is a statement that even larger files are no problem.
