How?

Hey, i have so many brushes and i would like to organize them in to different categories like grunges abstartct and so on how do i do that?

Just make new folders and such.

the bruses that are on my PS is there a way i can get them out to put them into folders?

i doubt it; just reanme them so it'd be like GRUNGE_wtvr or ABSTRACT_brshname
You get the point.
