I think this is your core problem.  Don't do that.

Something like this should work:

# Implement this properly
def html_escape(s)
  s
end

def recurse_dir(dirname)
  Dir.entries(dirname).sort.each do |filename|
    if FileTest.directory? filename
      puts "<div class=\"folder\">"
      puts "<div class=\"title\">#{html_escape(filename)}</div>"
      recurse_dir(filename)
      puts "</div>"
    elsif FileTest.file? filename
      puts "<span class=\"file\">#{html_escape(filename)}</span>"
    end
  end
end

recurse_dir("/wherever/you/start")
