windows 7 - How to delete Chrome temp data (history, cookies, cache) using command line

On Windows 7, I tried running this script but still cannot clear Chrome temp data. Can someone figure out what's wrong with the script? Where do Chrome store history and cache ? Thanks

taskkill /F /IM "chrome.exe">nul 2>&1

set ChromeDataDir=C:\Users\%USERNAME%\AppData\Local\Google\Chrome\User Data\Default
set ChromeCache=%ChromeDataDir%\Cache>nul 2>&1  
del /q /s /f "%ChromeCache%\*.*">nul 2>&1    
del /q /f "%ChromeDataDir%\*Cookies*.*">nul 2>&1    
del /q /f "%ChromeDataDir%\*History*.*">nul 2>&1
