I’am in front of the same Challenge… From my researching there is no way to use the native OS Fileexplorer, at least not for Runtime purpose…
Rama made a Tutorial for a selfmade Treeviewer, take a look at my last comment here: Ingame UE4, OS File browser file - Rendering - Unreal Engine Forums

So I think with the Blueprint-Only approach there is no solution implemented in the Editor yet. Please let me know if you come to another solution.
