inside the iTunes folder is sometimes a concern for some users of iTunes.
iTunes stores things in its own way and the important thing is how they are displayed in the iTunes application window itself.
In the main iTunes window, sort the view by Album and all the relevant tracks will be grouped together in albums.
Make playlists of each album will allow you to view each album separately.
Exporting to an SD card should not need the assistance of third party software.
Open the SD card window and drag what you want from iTunes to the SD card window.
