I'm making a bat file that can create a text file of any exact size and it will be compression resistant just for fun. It's currently in 2 parts because that's the only way I could figure out how to do it. I tried running the second part in a loop in the first one so I didn't need to use the call command but it didn't work.

The problem is that it takes forever and my CPU peaks at 31% so I'm wondering if there is a way to make it use the CPU more so it can execute faster or just make my code more efficient so it runs faster.

This is part one:

@set GB=1
@set TB=0
@set PB=0
@set /a "g=1*%GB%"
@set /a "t=1024*%TB%"
@set /a "p=1048576*%PB%"
@set /a "Total=%g%+%t%+%p%"
@set /a "c=%Total%*262144"
@set /a "d=%c%-1"
@echo on
@set /a "gTotal=%Total%/1"
echo %gTotal% GB
@set /a "tTotal=%gTotal%/1024"
echo %tTotal% TB
@set /a "pTotal=%tTotal%/1024"
echo %pTotal% PB
echo to create %gTotal%GB_RandPass.txt press any key
pause
@Echo Off

::set /P lengthnumberuser="What length do you want your password to be? "
::pause

Set _RNDLength=4101
Set _Alphanumeric=ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789
Set _Str=%_Alphanumeric%987654321
:_LenLoop
IF NOT "%_Str:~18%"=="" SET _Str=%_Str:~9%& SET /A _Len+=9& GOTO :_LenLoop
SET _tmp=%_Str:~9,1%
SET /A _Len=_Len+_tmp
Set _count=0
SET _RndAlphaNum=
:_loop
Set /a _count+=1
SET _RND=%Random%
Set /A _RND=_RND%%%_Len%
SET _RndAlphaNum=!_RndAlphaNum!!_Alphanumeric:~%_RND%,1!
If !_count! lss %_RNDLength% goto _loop
Echo Password is: is !_RndAlphaNum!
::pause
@echo %_RndAlphaNum%> %gTotal%GB_RandPass.txt
for /l %%x in (1, 1, %d%) do (
call "create_1GB-2EB_fileV4_Part2.bat"
)
:: @echo %_RndAlphaNum%>> %gTotal%GB_RandPass.txt

This is part 2:

@set GB=1
@set TB=0
@set PB=0
@set /a "g=1*%GB%"
@set /a "t=1024*%TB%"
@set /a "p=1048576*%PB%"
@set /a "Total=%g%+%t%+%p%"
@set /a "c=%Total%*262144"
@set /a "d=%c%-1"
::@echo on
@set /a "gTotal=%Total%/1"
::echo %gTotal% GB
@set /a "tTotal=%gTotal%/1024"
::echo %tTotal% TB
@set /a "pTotal=%tTotal%/1024"
::echo %pTotal% PB
echo createing %gTotal%GB_RandPass.txt Please wait.
