You use it to reject all elements from an Enumerable for which the block 
is true (to be more exact: not nil or false).

As an example:

numbers = 1..10
# get even numbers by rejecting all odd numbers
even = numbers.reject {|num| num.odd?}
p even

In your case you want to reject all files in a certain folder, so you 
might check if the current file path begins with the folder path:


ignore_folder = 'C:/folder/ignore'
copy_files = Dir["#{original_path}/**/*.*"].reject do |file_path|
  file_path.start_with? ignore_folder
end


However, this is not a perfect solution, because it will do an exact 
string comparison rather than actuall compare the folders. But it should 
work for a small script.
