Level Selection Menu That Updates

How would I go about making a menu that shows all of the levels in a certain folder? I want it to be easy to make new levels and play them so Steam Workshop could be implemented later on. How would I go through all of the levels in that folder, use a for each loop and add a widget for each one?

Hi! first you need to see if standard blueprint library allows you any manipulation with files,but I don’t think so.So you will need a plugins or write you own Blueprint function library over UE4 C++ file system.Here is the link to the API
