Adding music to zen from a different computer
I no longer have a personal computer but im able to use the computer at my work to add music to my zen. How can i do this without erasing all the music i already have stored on my player? On my old computer i was using the creative program to add music. I was planning on using wmp on this computer but im afraid that when it syncs it will either delete all the music on my player or add all the music from my player to the computer (which would take up too much space plus i have personal pictures and such). How can i transfer small amounts of music at a time to my zen without deleting what is already on there?
I tried the drag and drop method and i can never find the music again on my player...probably because i cant edit the song name/artist/etc without a program.
