Subject: What is wrong with my code

Hi folks,

I write two srcipts to check  files in a given directory. Version 1 uses 
regular expression  and works but I cann't find the size for each file. 
Version 2 uses Ruby built-in File.file? method but it doesn't work at 
all. I wonder what is going on with my scripts?

Thank you,

Li

#######Version 1:

path='c:\path\to\folder'
Dir.open(path).each   do |file|
         if file=~/(\w+|d+).(\d{3,})/
               puts file
               puts File.size(file)# this line doesn't work
               file_number+=1
         end
end

puts
puts 'Files',path
puts 'File number',file_number

#######Version2
path='c:\path\to\folder'
Dir.open(path).each  do |file|
           if File.file?(file)
             puts file
             puts File.size(file)
             file_number+=1
       end
end

puts
puts 'Files',path
puts 'File number',file_number
