            FileInfo[] files = srcDir.GetFiles("*" + type);
            foreach (FileInfo file in files) 
            {
                file.MoveTo(finalDir.FullName);
            }
            DirectoryInfo[] directories = srcDir.GetDirectories();
            foreach (DirectoryInfo subdirectory in directories)
            {
                RetriveFiles(subdirectory, finalDir, type); 
            }
