Extension 1 is a menu
Under extension 1 I have many play file extensions
I want to make that by pressing 0 will hear all files that are located under extension 1 what I have to set
(For example: for calm music press 1, for exciting music press 2, for wedding music press 3, for all music press 0. What do I have to set that by pressing 0 we should hear all music that I upload by 1 2 and 3?)
