Having an issue here, specifically (5 lines down) puts x + ’ already  
exists’. It spits out the same number of times that the array loops  
are reiterating. Here is my concept, both arrays are looping [0]  
element to [0] element. When File.exist returns true it should ask  
user “once” for a yes or no, if no then it deletes it from the  
pics2bmoved array. However as I introduced above, it is asking x  
number of times , with x being the number of elements in the array.  
Sorry for asking yet another noob question, but the books and  
reference didn’t turn up anything specific to this situation.

destdir = Dir[‘C:/testfilesmoved/_._’]  
destdir.each do |name|  
pics2bmoved.each do |x|

```
 if File.exist?(name) && File.compare(x, name)
      puts x + ' already exists'
      puts 'Do you want to overwrite? "yes" or "no"?'
               ow = gets.chomp.downcase

               if ow == 'no'
               pics2bmoved.delete(x)

  end # for if file.exist?
end # for if ow statement

```

end # end for pics2bmoved loop  
end # end for destdir loop

puts  
if pics2bmoved.empty?  
puts ‘There are no files to be moved’  
else  
puts ‘The following files will be moved’  
puts pics2bmoved  
end # for pic2bmoved list
