App Designer Drop Down Options from Folder

I am creating an app in App Designer and I was wondering if it was possible to create a Drop Down menu that is always updating with files from a designated folder as the options. I want to easily select these files and run them through the rest of my program. I am pretty new to Matlab and am hoping to get pretty detailed steps. I would be very grateful if somebody could help me out. Thank you!

'always updating' is a tricky concept. You probably don't want to check for new files every milisecond. I would suggest looking into timer objects.

Put the lines you want to run in a function and specify it as the TimerFcn property (this behaves the same as Callback functions, see the documentation for details and examples).
