Gail is correct, you need to restore things as they were. You can move drives/folders, but not files.
Is this a one time thing or do you do this often? If often, you might build a script that you save to do this. What you'd want to do is
- restore like this
- add new files as you want them
- move objects with index rebuilds or drop/create to the new files
- emptyfile and drop the old files.
Are you looking to create new filegroups or just reorganize the files you have in a different way?
