Batch File Or script Required

[healtheworld]

Hello friends,
I hv two folders on my windows xp c: drive both contain 50 to 60 same folders . Now i hv to create a batch file which will copy all files from each subfolder in each folder to a new folder such that it only copies the unique file from each folder to newly created folder.
Example

folder 1
subfolder
file1 file2


folder 2
subfolder
file1 file3

the new folder should be
newfolder

subfolder
file1 file2 file3


Any help will be highly appreciated..
