Hi EB,

I figure out why it doesn't work: irb only looks for the file name in 
current directory. I try on both linux and xp.
But the files I want to search are in a different drive under XP. 
Actually   this question comes from the following script1 and script2:

########### script1--It works perfect.
file_number=0
path="I:\\Common\\Gao\\Notebooks\\Flow\\OT1\\OTI-4"

Dir.foreach(path)   do |file_name|

      if file_name=~/(\w+|d+).(\d{3,})/
          puts file_name
          file_number+=1
      end
 end

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

############Screen ouptut
C:\Ruby\self>dir5.rb
OTI-4.001
...
OTI-4.025
OTI-4.026

Files
I:\Common\Gao\Notebooks\Flow\OT1\OTI-4
File number
26

####script2--Doesn't work

file_number=0
path="I:\\Common\\Gao\\Notebooks\\Flow\\OT1\\OTI-4"

Dir.foreach(path)   do |file_name|

        if File.file?(file_name)
             puts file_name
             puts File.size(file_name)
             file_number+=1
        end
 end

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

##screen output

C:\Ruby\self>dir5.rb

Files
I:\Common\Gao\Notebooks\Flow\OT1\OTI-4
File number
0

But right now I just don't know how to make script 2 work.
