Eg: folder1(2 files) -----> folder2(4 files) and folder2 is inside folder1. total count for above case should be 6 files.

A slight modification and a comment

Dir['**/*'].count { |file| File.file?(file) }

works for me in Ruby 1.9.3, and is shorter.

A caveat, at least on my Windows 7 box, is that Dir['somedir/**/*'] doesn't work. I have to use

cd(somedir) { Dir['**/*'] }
