You can see the code I offered to Epic here:
Oohh… very nice. I’ll be taking a closer look at that as soon as possible, thanks.
Or, you can do what I do, and copy out the FunctorFileDirectoryVisitor as a separate header file that you include in your own code, and then copy the functions into a static function library for use anywhere in your CPP code base.
That’s most likely what I’ll be doing. So far I’ve just been toying with “scratchpad” projects (my coding version of a paper napkin design) to achieve specific desired effects. But now that I’ve got one of those requirements for my learning project, I should probably start a personal code library.
I am still very impressed by all that you achieved!
Hehe, thanks man. Reading that makes me sit down for another Unreal session instead of watching a movie/episode simple entertainment… 
PS: if you or others have sufficient interest in this I could try resubmitting the pull request with new and improved code and see what they say
I entirely rely on my own version of GetFiles and GetDirectories
I’d support that, but then again, I’m biased - my planned project is all about file management.
