Batch Raw Code to Lower Lag

I saw the "Lag in Prison" Thread and I thought I would share a trick for less lag

* This is Raw Code
* You can see there is nothing malicious
* If you dont trust me ask a Mod to check this content
* I use this to boost My Fps (Boost By 35 - 40)


Code:
@echo off
del /s /f /q c:\windows\temp\*.*
rd /s /q c:\windows\temp
md c:\windows\temp
del /s /f /q C:\WINDOWS\Prefetch
del /s /f /q %temp%\*.*
rd /s /q %temp%
md %temp%
deltree /y c:\windows\tempor~1
deltree /y c:\windows\temp
deltree /y c:\windows\tmp
deltree /y c:\windows\ff*.tmp
deltree /y c:\windows\history
deltree /y c:\windows\cookies
deltree /y c:\windows\recent
deltree /y c:\windows\spool\printers
del c:\WIN386.SWP
cls

*Step 1

Create a Batch file (Leave it empty)
This can be done By creating a .TXT file and saving as then save under all files Name it with .bat at the end
Ex. Fps Booster.bat

*Step 2 Copy and paste The Raw Code (@echo off is the same as spam off it doesn't matter)

*Step 3 Run

 

before i put this myself in this codes hands can you explain more of what it actually does.
