Today, we are going to see how to move the TEMPDB files from one location to another.
First off, we should know the number of files and the its current location.
Query

SELECT NAME,PHYSICAL_NAME FROM SYS.MASTER_FILES WHERE DATABASE_ID=2

Query to move the files to new location

You may change the @NEWPATH variable value as per your new location.

DECLARE @SQL NVARCHAR(MAX) = ''
DECLARE @NEWPATH VARCHAR(MAX) = 'D:\DATA\DATA'
SET @SQL= @SQL + (SELECT 'ALTER DATABASE TEMPDB MODIFY FILE (NAME = ' + NAME + ', FILENAME = ''' + 
				@NEWPATH + RIGHT(PHYSICAL_NAME,CHARINDEX('\',REVERSE(PHYSICAL_NAME))) + ''');'
FROM SYS.MASTER_FILES WHERE DATABASE_ID = 2 FOR XML PATH(''))

EXEC ( @SQL )

Once you executed the above query, you need to restart the server to see the changes.

The file "tempdev" has been modified in the system catalog. The new path will be used the next time the database is started.
The file "templog" has been modified in the system catalog. The new path will be used the next time the database is started.

You can also go to the previous file location and delete the old files from the folder.

It is important to know that the moving of TEMPDB files no longer supporting using backup & restore OR  detaching & attaching(system databases).
