What method are you using to transfer your music to your 4700?
For an example of one way I transfer files:
I open two windows by clicking on "My Computer" then I navigate in one window to the location of the files on my pc and in the other window I navigate to Pocket PC and then I drag and drop the files I want to move
When you navigate to Pocket PC you can select the location you want your files moved to such as Ipaq File Store, SD Card, CF Card etc.
If you aren't clear on Ipaq File Store or how memory works go to the left and click on "MY PDA", scroll down under Tip, Tricks & FAQ's to the entry on memory and it has a link to a great explanation!
Hope this helps and if not expand on your question.
