Get root,child,child,child and so on

how could i get my taxonomies from SharePoint Root has 3 folders, inside this folders i have more folders and inside the second folders i have more folders and so on,

class Program
{
    static void Main(string[] args)
    {

        using (SPSite site = new SPSite(@"http://mysite.local/"))
        {

            SPWeb web = site.OpenWeb();

            TaxonomySession taxonomySession = new TaxonomySession(site);
            TermStore termStore = taxonomySession.TermStores[0];
            Group group = termStore.Groups["MyGroup"];
            TermSet termSet = group.TermSets["terms"];

            foreach (Term termRoot in termSet.Terms)
            {

              foreach (Term subfolders in termRoot.Terms)
              {



                      System.IO.DirectoryInfo di = new System.IO.DirectoryInfo(@"C:\" + termRoot.Name);
                      if (di.Exists == false)
                          di.Create();
        System.IO.DirectoryInfo dis = di.CreateSubdirectory(subfolders.Name);


              }

              }


            }

        }


    }

Right now my code create root folders and subfolders, root1 and level1 of subdirectory, but i also want to get the taxonomies from my level1 subdirectory how could i do that? so i want to use create subdirectories 2 times?
