I've found solution. It's property DirsOnTop in packages/filemng.
I've founded that you have to install additional packages in order to work inside Builder.
But, looking that sorting function(handler) is difficult for me.
I want to implement directory/files alphabet sorting regardless is it directory (not before files).
Is there someone who can help me? :)
I want to change sorting function in direcory listing.
In which source file I can find that code?
Building from command line (simply make) works,
but building from Builder doesn't.
Maybe I have problem with Builder.
Is it works?
