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>
  </div>
</div>




the indentation could be improved... but i suppose that doesn't matter  
for html anyhow.
