Subject: cp_r is not working

Hi,

I'm trying to build a program which copy from source folder to dest
folder.
I did it in File-After-File methond which mean I inserted all the file
names into an Array and then make a cp_r on each file.

It's not working and I get errors of Folder Duplication.
I can't understand why, I'm kinda new to Ruby.

Here is my code:

require 'FileUtils'

time = Time.now.strftime('%Y-%m-%d')
srcPath = "C:/Users/eliranbz/Desktop/Test"
destPath = time + '/'
#Create the Files Array
theFiles = []
#Check if folder exist
if File.exists?(destPath) && File.directory?(destPath)
    puts 'Folder could not be created - Already exist'
  puts 'Folder has been created: ' + destPath
else
  FileUtils.mkdir time
  puts 'Folder has been created: ' + time
end
#Just to know how much files I have in the Directory
filesCount = Dir.entries(srcPath).size - 2
puts 'files count: ' + filesCount.to_s

#Insert File by File to the Array

Dir.foreach(srcPath) {
|x| theFiles << x
puts x
}

puts 'Files has been inserted to Array'

#Make a copy on each file value in the array

theFiles.each do |y|
  FileUtils.cp_r y, destPath + y
end


I get the error:

C:\Users\eliranbz\Desktop>ruby createFolder.rb
Folder could not be created - Already exist
Folder has been created: 2011-02-02/
files count: 17

Please advice.
