How to move Tempdb to another Drive.

USE TempDB GO EXEC sp_helpfile--By this we can find where the .mdf and .ldf files are placed defaultly. GO USE master GO ALTER DATABASE TempDB MODIFY FILE (NAME = tempdev, FILENAME = 'D:\30-04-2009BAK\Tempdb\datatempdb.mdf') GO ALTER DATABASE TempDB MODIFY FILE (NAME = templog, FILENAME = 'E:\TempdbLog\datatemplog.ldf') GO After running the above query Stop and Restart the services. 
USE master
GO
ALTER DATABASE TempDB MODIFY FILE
(NAME = tempdev, FILENAME = 'D:\DATA\tempdb.mdf')
ALTER DATABASE TempDB MODIFY FILE
(NAME = temp2, FILENAME = 'D:\DATA\tempdb_mssql_2.ndf')
ALTER DATABASE TempDB MODIFY FILE
(NAME = temp3, FILENAME = 'D:\DATA\tempdb_mssql_3.ndf')
ALTER DATABASE TempDB MODIFY FILE
(NAME = temp4, FILENAME = 'D:\DATA\tempdb_mssql_4.ndf')
GO
ALTER DATABASE TempDB MODIFY FILE
(NAME = templog, FILENAME = 'D:\DATA\templog.ldf')
GO
After this change stop and start the services and you can see the data files of temp databases in respective path.
