Thanks Daniel for your input. I tried using /\d+/ but it'll extract 
files that have even 2 numbers to i decided to use 
/(\d\d)(\d\d)(\d\d\d\d)/ instead. It enabled me to run the command on 
certain files but not all files and the following error occured:

        from testing.conf.rb:162:in `delFiles'
        from testing.conf.rb:204

Is there anything wrong with mycode that prevents deleting all the files 
that I want?
