    filelist = os.listdir(path)
    for filename in filelist:
        de_path = os.path.join(path, filename)
        if os.path.isfile(de_path):
            if de_path.endswith(".txt"): #Specify to find the txt file.
                ret.append(de_path)
        else:
            findtxt(de_path, ret)
