Moving the tempdb database to another location

Here are the steps to move the tempdb to another location

1. Determine the logical and physical filename of tempdb using sp_helpfile

use tempdb
go
sp_helpfile
go
image

2. Now use the ALTER database and specify the FILENAME parameter to the location where you want to move each file.

USE master
GO
ALTER DATABASE
tempdb
MODIFY FILE (name = tempdev, filename = 'D:\Data\tempdb.mdf')
GO
ALTER DATABASE
tempdb
MODIFY FILE (name = templog, filename = 'D:\Data\templog.ldf')
GO

You will receive a message similar to the following “File 'tempdev' modified in sysaltfiles. Delete old file after restarting SQL Server.”

3. Stop and then restart SQL Server.
