Although you still have the 3 users folders, they are not the same users. Windows uses a unique number each time you create an account. The rights to files created in the users 'home' directory are to that unique number, not the username. The only way I can think that you can do this is to use the Administrator user, copy the files to a public directory, login as the new user and copy the files back to the users directory. You make have to take ownership of the files, too.
