Folder manipulation

Question

Hi.

I have two paths: C:\Test\New Folder2
                           C:\Test\New Folder2\New Folder\a

I would like to gradually make the first path look like the second path. So the first step woould be:    C:\Test\New Folder2New Folder
                                        C:\Test\New Folder2\New Folder\a

And the second would be:   C:\Test\New Folder2New Folder\a
                                          C:\Test\New Folder2\New Folder\a

Do u have any ideas?
