I get the error in Windows 7 zip and 7zip when exctracting splitted archive from directory. I set max size to 5 mb. When archive is smaller everything goes fine, but if splitted only win-rar can extract the archive.

My code is very simple (as in examples):


public string DoSplit(int maxSize)
            using (ZipFile zip = new ZipFile())
                zip.CompressionLevel = Ionic.Zlib.CompressionLevel.BestCompression;
                zip.MaxOutputSegmentSize = maxSize; //5mb

                DirectoryInfo commonWorkingDir =  Directory.GetParent(_workingPath);
                DirectoryInfo workingDir = new DirectoryInfo(_workingPath);

                _zippedDirectory = Path.Combine(commonWorkingDir.FullName, workingDir.Name + zippedSuffix);
                zip.Save(_zippedDirectory + "/");

            return _zippedDirectory;
