Three ways (at least) to do this:

1: Using Dir.glob:
file_list = Dir.glob('**/*').select{|filename| 	
	File.file?(filename)}

2: Using Find:
file_list = []
Find.find('/') {|path| file_list << path if File.file? path}

3: Using /usr/bin/find:
file_list = `find . -type f`.split

Once you've got file_list, you can take file_list.length to get the 
number of files.  If you want to avoid having an intermediate array, you 
  could use Find this way:

file_count = 0
Find.find('/') {|path| file_count += 1 if File.file? path}
