Is it possible to add or delete pagefile.sys size and partiotion with DOS?

[ionic]

Here is what I'd like to accomplish. I can do some DOS batch stuff, but other than that I am a brainless ol fart.

I have two partitions setup with aprox. 4GB each, named PageFile_1 and PageFile-2. I'd like to use only one of them at any
given time.

Every couple of weeks, I would like to unallocated from one partition and allocate to the other partition. After this is done I would
like to securely wipe the recently used partition so that it is ready for the next swap.

Is this possible via DOS only? I know I can wipe the free space with systernals  "sdelete" via a batch file, just don't know if allocating and unallocating the pagefile.sys from partition to partition is possible.

Could use some insight with this.

Thanks

Perhaps something like this:

Code: [Select]

===== BATCH SCRIPT BEGIN =====
@echo off
goto menu
:menu
echo.
echo What would you like to do?
echo.
echo Choice
echo.
echo Change Pagefile.sys from Drive E: to Drive G: or visa versa
echo q Quit

echo.

:choice
set /P C=[e,g,q]?
if "%C%"=="q" goto quit
if "%C%"=="g" goto SetG
if "%C%"=="e" goto SetE
goto choice


:SetG
echo Set Pagefile.sys to Drive G: at 3000, 3000?
pause
cls
regedit.exe /s DriveG_PageFileSize.reg
pause
goto menu

:SetE
echo Set Pagefile.sys to Drive G: at 3000, 3000?
pause
cls
regedit.exe /s DriveE_PageFileSize.reg
pause
goto menu

:quit
exit
:end
===== BATCH SCRIPT END =====

DriveG_PageFileSize.reg

Code: [Select]

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management]
"PagingFiles"=hex(7):47,00,3a,00,5c,00,70,00,61,00,67,00,65,00,66,00,69,00,6c,\
  00,65,00,2e,00,73,00,79,00,73,00,20,00,33,00,30,00,30,00,30,00,20,00,33,00,\
  30,00,30,00,30,00,00,00,00,00

DriveE_PageFileSize.reg

Code: [Select]

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management]
"PagingFiles"=hex(7):45,00,3a,00,5c,00,70,00,61,00,67,00,65,00,66,00,69,00,6c,\
  00,65,00,2e,00,73,00,79,00,73,00,20,00,33,00,30,00,30,00,30,00,20,00,33,00,\
  30,00,30,00,30,00,00,00,00,00
I would have to reboot before running sdelete.exe to wipe the cleared drive.

The next question, one that arises after exporting the .reg key is: why does the following line...

Code: [Select]

NAME             TYPE             DATA
PagingFiles      REG_MULTI_SZ     E:\pagefile.sys 3000 3000

appear as...

Code: [Select]

"PagingFiles"=hex(7):45,00,3a,00,5c,00,70,00,61,00,67,00,65,00,66,00,69,00,6c,\
  00,65,00,2e,00,73,00,79,00,73,00,20,00,33,00,30,00,30,00,30,00,20,00,33,00,\
  30,00,30,00,30,00,00,00,00,00
...and, is there a way to get the .reg file in the first format, so that it is editable?
