Files in folder Windows.old in Vista

I have installed Ultimate on a Business version and then received the
Windows.old folder. I want to delete it but have found same working files in
old path than in the new. It appears that Windows updates the working files
in both folders. Are they mirrored or copies. I changed the name of one file
in old - corresponding file in the new folder received the same name. If I
delete files from Windows.old will they be deleted from current folder too?
