ListView with list of names of files

In a ListView I would like to put the list of the files (.m4a or .mp3) that are in a specified directory (ex. /SDcard/ or other). Would you help me, please? Thank you.

Use Taifun’s File Extension to return a list of files by directory and extension (if you need more than one extension then just run the call again with the second extension and add to the same list) - follow the guidance on the extension page…
