issue with rd cmd in a batch file

ok so basicly i made a batch file to automate some basic system mainenance the problem is i cant get it to clean up after its self.

i am packaging it in and sfx archive using winrar the problem is that i want it to remove the folder it was extracted to after running for easy clean up but it will either not work all together or it will just delete the files and leave the directory saying its in use any suggestions? here is the code so far

Code:

@echo off

echo                        Welcome to the automated maintenance 
echo.   
echo   This file will only work properly on an account with administrative privliges
@ping 127.0.0.1 -i 8 >nul
cls

:start
echo What maintenance would you like to run on this system?
echo.   
echo [d] defragment a system drive
echo [c] check disc for consistency
echo [r] clean RAM to increase system performance
echo [e] exit

>nul set /p "answer=what maintenance would you like to run on this system? [c/d/a/] "
if /i "%answer%" == "c" goto :check disk
if /i "%answer%" == "d" goto :defrag
if /i "%answer%" == "a" goto :anti-virus
if /i "%answer%" == "r" goto :ram
if /i "%answer%" == "e" goto :end
echo invalid choice
goto :start

:check disc
cls
echo What would you like to do?
echo. 
echo [r] retrive redable data from damaged sectors
echo [f] fix errors found on disk
echo [e] exit

>nul set /p "answer=would like to run chkdsk? "
if /i "%answer%" == "r" goto :repair
if /i "%answer%" == "f" goto :fix
if /i "%answer%" == "e" goto eof
echo invalid option
goto :check disc


:fix
chkdsk /f
goto :end

:repair
chkdsk /r
goto :end


:defrag
cls
echo What disk drive would you like to defragment?
echo.
>nul set /p "answer=What disk drive would you like to defragment? "
echo --------------------------------------------------------------------------------
echo your choice is %answer% is this correct? [y/n]
>nul set /p "answer2=see if this is correct drive. "
if /i "%answer2%" == "y" goto :run
if /i "%answer2%" == "n" goto :defrag
echo Invalid option
goto :defrag

:run
defrag %answer%:
goto :end

:ram
cls
echo Are you sure you want to do this? [y/n]
>nul set /p "answer=Are you sure? "
if /i "%answer%" == "y" goto :run2
if /i "%answer%" == "n" goto :end
echi invalid option
goto :ram


:run2
>nul start /wait "clean ram.vbs" "C:/temp/clean ram.vbs"
echo proccess complete press any key to exit.
>nul pause


:end
start cmd.exe /c rd /s /q c:\temp
exit

 

I'm thinking it won't delete the working directory. Try
cd ..
or
cd \
before removing the extracted directory.

 

worked perfectly once i alterd the end cmd a bit changed it to c:\ as the directory and then ran remove cmd without initating another cmd window


so thank you very very much it worked perfectly and sorry for late reply since it was a side project i hadnt had time to repackage it and try
