sql server 2005的tempdb太大了

sqlserver 2005装在c盘，用久了竟然30g的c盘不够了，检查发现tempdb占了11G
赶快找下怎么把tempdb弄走

USE master

GO

ALTER DATABASE tempdb modify file (name = tempdev, filename = 'F:\Sql Server TempDB\Pathtempdb.mdf' )

GO

ALTER DATABASE tempdb modify file (name = templog, filename = 'F:\Sql Server TempDB\Pathtemplog.ldf' )

重启sqlserver，已经到了新路径。旧tempdb删掉，ok。
