Question

Why does below class output directory’s as well as filenames on line “print “\n”+f” ?
I just want to output the files but directories are also being outputted.

class Sort



  require 'find'

  directoryToSort = "c:\\test"

   total_size = 0

   Find.find(directoryToSort) do |path|
     if FileTest.directory?(path)
       if File.basename(path)[0] == ?.
         Find.prune       # Don't look any further into this directory.
       else
       Dir.foreach(path) do
       |f|
       # do whatever you want with f, which is a filename within the
       # given directory (not fully-qualified)
         if !FileTest.directory? f
         print "\n"+f
         end
       end
         next
       end
     else
     end
   end

end

It says right there in a comment:

# do whatever you want with f, which is a filename within the
# given directory (not fully-qualified)

key being “not fully-qualified” part. you need to do something like:

if !FileTest.directory? (path + File::SEPARATOR + f)
