tune identification on clip

hi

   new to the forum and   and of mature years, so be patient with me, ok. I have downloaded all my jazz numbers onto my clip it is just some of them are named with the artist and others are  just Track 01,02 ,etc . Yet when i look at the files on WM11  they show there artist name . Could you help  how to name them as i want

                  regards 

sorry they appear on windows explorer as named artists but just numbers  (TRACK01)  on wm11
