Move data from NDF file to MDF file

I have a database which has two data files, MDF and NDF.
The question is how can I move data in NDF into MDF file,
so I could delete the NDF file from the database.
Thanks
ALexHi,
I HAVE ALREADY REPLIED TO UR OLD POST.
EMPTY FILE:
Migrates all data from the specified file to other files . This option
allows the file to be dropped using the ALTER DATABASE statement.
THANKS
