You are probably using the wrong api.  If you want to get a list of
files/directories in a single directory, you should use:
Dir.entries()
or
Dir.foreach() for more complex iterations.

Find does a recursive search across multiple directories (and
subdirectories).

That being said, files are read and returned as your OS does.  So it
is up to you to sort them out into directories and not directories and
to sort them out.  You can usually do that with arrays.

dir = Dir.pwd

#
# dirs and files sorted together
#
puts Dir.entries(dir).sort

#
# or... more complex...
#
dirs  = []
files = []
Dir.foreach(dir) do |file|
   next if file =~ /^\..?$/ # ignore . and ..
   if File.directory?("#{dir}/#{file}")
      dirs << file
   else
      files << file
   end
end
dirs.sort!
files.sort!
puts dirs, "---", files

#
# or same, but simpler (more ruby-like)
#
all = Dir.entries(dir) - ['.', '..']
all.sort!
dirs = all.select { |x| File.directory?("#{dir}/#{x}") }
files = all - dirs
puts dirs, "---", files
