tempdb files

Hi

I have created new files for tempdb database, now I want the old temp files should be deleted upon the restart.

Earlier I have two files in tempdb : tempdev.mdf and templog.ldf in X:\TEMPDB

Now I created new files in this tempdb : tempdata1.mdf,tempdata2.ndf,templog1.ldf in L:\PRDDATA.

Now I want once I restart database the tempdb should not read the old files which are in X:\TEMPDB. they should read from L:\PRDDATA.

Please suggest

Regards
