Exporting Folder that has multiple mp3 file inside

Hello, I have a folder that has multiple mp3 files inside. I want to export this folder to a location wherever user wants with an extension (I don't know which one would be best). That exported folder must be reusable. I mean I must be able to import that exported folder into another device to use mp3 files that it stored. So how can I export this folder in swift ? Any idea would be great. Thanks in advance
