Is it possible to restore a database's logical path to multiple physical files?

The following produces an expected file or id error message.

RESTORE DATABASE TestDB
FROM DISK = 'Z:\SQLServerBackups\AdventureWorks2012.bak'
WITH MOVE 'AdventureWorks2012_Data' TO 'C:\MySQLServer\testdb.mdf', 'C:\MySQLServer\testdb2.ndf',
MOVE 'AdventureWorks2012_Log' TO 'C:\MySQLServer\testdb.ldf';
GO

Not possible. A restore recreates the DB as it was at the time of backup. If the database that was backed up had one data file then the restored database has one data file.

If it is not possible to restore to multiple files, is it possible to automate moving the data to multiple ndf files after the restore?

Depends what you want to do specifically (and why)

There's no ALTER DATABASE SPREAD DATA ACROSS FILES command.
