MicroSDHC question

I have a 4gb card that I’m putting audio books on. (As well as other cards with other things on them). I just switch out the cards as I need to. 

  I got several from LibriVox, a free volunteer service.  On this site not all readers are professional or that great and different chapters may be read by different readers but they do pretty good.  They do the old, out of copywrite, books.  The classics.  And some good ones … ;)  .  I finally listened to Wizard of Oz which I had been meaning to read forever. 

I save them to my hard drive, put them Windows Media Player 10 and then sinc to my Fuze.
