Subject: Progressbar while file/folder copy in progress.

I would like to have a progress bar for my application while file/folder
copy is in progress. Is it possible to use "FileUtils.cp_r" in
background. So that it create different process and i can loop it to
compare initial & current size for incremental integer value. The work
flow i am expecting is as follows:-

initial_file_size
   create_copy_process_bg (copy)
   while copy exist
       check_current_file_size
       calculate_presentage_value
       #use persentage integer value to set progressbar on gui.
   end

What i find it difficult is to run "FileUtils.cp_r" as different process
in background.
