Hi Robert,

Thank you very much for the code. Based on what I understand and what I 
need I make some changes. But I still have some questions:1) How do I 
factor the print or format codes here? 2) The outputs of the file  are 
in reverse order how do I print them out in this format; xxx.001, 
xxx.002,...,xxx.026 3) what is the purpose of File.basename here?

Thanks,

Li


#dir6.rb find the file number in a folder
require 'find'

path='I:/Common/Gao/Notebooks/Flow/OT1/OTI-4'


file_number = 0
Find.find(path) do |f|
   #sum += File.size(f) if
   #  /(\w+|d+).(\d{3,})/ =~ File.basename(f) && File.file?(f)
   #puts f if /(\w+|d+).(\d{3,})/ =~ File.basename(f) && File.file?(f)
   if File.file?(f) && f=~/(\w+|d+).(\d{3,})/
   		print f,"\t"
   		printf("%10s %10s", File.size(f),'byte' )
   		puts
   		file_number+=1
  end
end

puts file_number

###screen output
