I found a good program to delete temp files, small and fast. I would like to share it with others.  Open a new file, add contents as below. **************************************************************************
　.@echo off

　　echo CLEARING PLEASE WAIT......

　　del /f /s /q %systemdrive%＼*.tmp

　　del /f /s /q %systemdrive%＼*._mp

　　del /f /s /q %systemdrive%＼*.log

　　del /f /s /q %systemdrive%＼*.gid

　　del /f /s /q %systemdrive%＼*.chk

　　del /f /s /q %systemdrive%＼*.old

　　del /f /s /q %systemdrive%＼recycled＼*.*

　　del /f /s /q %windir%＼*.bak

　　del /f /s /q %windir%＼prefetch＼*.*

　　rd /s /q %windir%＼temp & md %windir%＼temp

　　del /f /q %userprofile%＼cookies＼*.*

　　del /f /q %userprofile%＼recent＼*.*

　　del /f /s /q "%userprofile%＼Local Settings＼Temporary Internet Files＼*.*"

　　del /f /s /q "%userprofile%＼Local Settings＼Temp＼*.*"

　　del /f /s /q "%userprofile%＼recent＼*.*"

　　echo FINISHED
　　echo. & pause

Save type "all files", name as "clear temp.bat" . Double click the file, it will clear your temp in a short time. Perfect!
