Ionic.Zip.ZipException C#

Aug 17 at 8:11 AM
Hello,

I have this code to decrypt and unzip my files but i get an error on my extractall that ionic zip is not supported by DotNetZip: PKWare AES256?

Any solutions?

foreach (var file in Directory.GetFiles(inPath, "*.zip"))
        {
            string dest = file;

            //Decrypt file using Ionic.Zip.dll.
            using (ZipFile zfile = ZipFile.Read(file))
            {
                zfile.Password = "";                   
                zfile.ExtractAll(Path.GetDirectoryName(file));

            }

            dest = Path.Combine(donePath, Path.GetFileName(file));

            if (File.Exists(dest))
                File.Delete(dest);

            //Move the zip file to Done leaving the unzipped file for handling.
            File.Move(file, dest);
        }
