The question:
Why isn't it doing them like nested folders? I'd like to get
.-----------------
Parent folder
.------------------

> child files

__________
but I don't. Can anyone see whats wrong here? I'm losing my mind.
Thanks.
Where are the unit tests?

That's a good question, a fair question, and I would love to anwser it.

It probably just a matter of counting the divs. I've sort of hacked
together a rewrite that looks like it's getting it right. Emphasis on
"hacked" 
There's room for refinement, but anyway, this might get
you moving. http://pastie.org/188490

it looks like you are making it much harder than it needs to be... this code gives you the depth you are at all the way down without the need to count:
cfp:~ > find a
a
a/b
a/b/c
a/b/c/file.rb
a/b/file.rb
a/file.rb
cfp:~ > cat a.rb
def div folder = '.', depth = 0
title = folder
entries = Dir[ "#{ folder }/*" ]
padding = ' ' * depth
files = entries.select{|entry| test ?f, entry}
dirs = entries.select{|entry| test ?d, entry}
dir_content = dirs.map do |dir|
div dir, depth + 1
end
file_content = files.map do |file|
content = <<-html
<span class='file'>#{ file }</span>
html
end
content = <<-html
<div class='folder'>
<div class='title'> #{ title } </div>
#{ file_content }
#{ dir_content }
</div>
</div>
html
indent = content[%r/^\s*/]
content.strip.gsub %r/^#{ indent }/, padding
end
puts div( ARGV.shift )
cfp:~ > ruby a.rb a
<div class='folder'>
<div class='title'> a </div>
<span class='file'>a/file.rb</span>
<div class='folder'>
<div class='title'> a/b </div>
<span class='file'>a/b/file.rb</span>
<div class='folder'>
<div class='title'> a/b/c </div>
<span class='file'>a/b/c/file.rb</span>
</div>
</div>
</div>
</div>
the indentation could be improved... but i suppose that doesn't matter for html anyhow.
regards.

we can deny everything, except that we have the possibility of being better. simply reflect on that.

The anwser to Phlips question is 'I don't know how to write unit
tests.'

That works, perfect. David, thanks. Looks like the num function was
the problem. I couldn't see it - the array intersection wasn't even
part of the equation.

And I guess you'd like to know how to do that?
Well, Ruby ships with Test::Unit
http://ruby-doc.org/core/classes/Test/Unit.html
Then, there's Shoulda:
RSpec:
Just to name three options you have. 
Ruby on Rails books usually cover Unit Testing (though, Rails brings its
own additions to the framework!).
And here's a quick guide to unit testing in Ruby:
