    "Description": "Hello there,\n \nI have a Zip file with the following structure:\n \nf01.jpg\nf02.jpg\nf03.txt\n \nI want to separate the files by extension, each one in your right Zip file. I tried to do this with the code below\n \n            using (ZipFile zipFileSource = ZipFile.Read(@\"D:\\Zips\\ZipSource.zip\"),\n                zipFileJPGs = new ZipFile(),\n                zipFileTXTs = new ZipFile())\n            {\n                foreach (ZipEntry zipEntrySource in zipFileSource)\n                {\n                    if (zipEntrySource.FileName.EndsWith(\"jpg\"))\n                    {\n                        zipFileJPGs.AddEntry(zipEntrySource.FileName, zipEntrySource.OpenReader());\n                    }\n                    else if (zipEntrySource.FileName.EndsWith(\"txt\"))\n                    {\n                        zipFileTXTs.AddEntry(zipEntrySource.FileName, zipEntrySource.OpenReader());\n                    }\n                }\n \n                zipFileJPGs.Save(@\"D:\\Zips\\ZipJPGs.zip\");\n                zipFileTXTs.Save(@\"D:\\Zips\\ZipTXTs.zip\");\n            }\n \nbut I didn't have sucess.

You can workaround it easily... its the same bug again we seem to discover again and again.\r\nadd this to your code:\r\nzipFileTXTs.ParallelDeflateThreshold = -1;\r\nzipFileJPGs.ParallelDeflateThreshold = -1;\r\nbefore you call zipFileTXTs.Save(...);",
