      Shl = new Shell();
      Folder Recycler = Shl.NameSpace(10);
      for (int i = 0; i < Recycler.Items().Count; i++) {
        FolderItem FI = Recycler.Items().Item(i);
        string FileName = Recycler.GetDetailsOf(FI, 0);
        if (Path.GetExtension(FileName) == "") FileName += Path.GetExtension(FI.Path);
        //Necessary for systems with hidden file extensions.
        string FilePath = Recycler.GetDetailsOf(FI, 1);
        if (Item == Path.Combine(FilePath, FileName)) {
          DoVerb(FI, "ESTORE");
          return true;
