You can move tempdb files by using the ALTER DATABASE statement.

1.	Determine the logical file names for the tempdb database by using sp_helpfile as follows: use tempdb go sp_helpfile go The logical name for each file is contained in the name column. This example uses the default file names of tempdev and templog.
2.	Use the ALTER DATABASE statement, specifying the logical file name as follows: use master go Alter database tempdb modify file (name = tempdev, filename = 'E:Sqldatatempdb.mdf') go Alter database tempdb modify file (name = templog, filename = 'E:Sqldatatemplog.ldf') go You should receive the following messages that confirm the change: Message 1 File 'tempdev' modified in sysaltfiles. Delete old file after restarting SQL Server. Message 2 File 'templog' modified in sysaltfiles. Delete old file after restarting SQL Server.
3.	Using sp_helpfile in tempdb will not confirm these changes until you restart SQL Server.
4.	Stop and then restart SQL Server.
