I made an mp3 player that populates a list with filenames from an xml file but I want to be able to display the contents of a folder in a list. basically populate the list from a directory insread of from the xml.
Flash doesn't allow you to access the local file system in that way. You should look into AIR, as it allows you to do this type of thing. Since AIR is also AS3 based, you won't need to change much code at all, if any. You'll just need to implement the local storage access part.
