Subject: Re: Cover a directory and put all the stuff in a TreeView


Call a function recursively when you hit a directory. This will output 
something as you mention below, I am just using Dir[*] to get a list of 
files:

def scan_files(dir, level=0)
  puts "#{' '*level}#{dir}"
  Dir["#{dir}/*"].each do |f|
    if File.directory?(f) then
       scan_files(f, level+1)
    else
      puts "#{' '*level}#{f}"
    end
  end
end

scan_files('/home/someone')
