I'm building a new program, which creates files in nested folders to create
a hierarchical data structure.

I have no problem with creating new folders, and creating files within those
folders.

However, it would be nice if I could create folders with customised icons. I
know I can paste icons on top of the stock ones, but thi is not what I want.
I want to be able to do it automatically within FB. Anyone ever done this,
or knows how ?

TIA,

Phil.
