After I can create and check if a directory exists I want to be able to read them. This I need, because I want to know how many albums I have, what their names are and I need the first image. The image I would like to use as a representation for the album - it is always better to have an image.

Good how can I do this? I need a data-container which holds all information and can be used to generate the album-list.

Again, I dont know if this would be coders best practice, but for me as a designer it works What did I do?
I created a Bindable ArrayCollection which I can use in the MXML as data provider. The I created the function getAlbumList() here I want to get the album names, file names and the path to the image file.
