Subject: Re: Dir.glob finding folders

Just to follow up, I did try this and it worked. I also want to add
that the reason I was trying to use Dir is because in searching for
solutions to this I found reference to it being faster. I would still
love to hear any feedback on how to optimize this or change the
solution so that it would speed things up. Searching a 60gb hard drive
this way takes a while. :)

Anyway, my solution that eventually worked:

require 'find'

file = File.open("projects.txt", "w")
print "Enter Drive Letter: "
drive_letter = gets.chomp
Find.find("#{drive_letter}:/") do |path|
  if FileTest.directory?(path)
    if path =~ /CFI-/
      file << "#{path} \n"
    end
  end
end

Thanks!

Geoff
