John,
I'm not sure this is the file you want but worked for me (don't remember where I downloaded it from) :

*regextension.bat
@echo off
setlocal
if {%1}=={} goto syntax
set ext=%1
if {%ext:~0,1%} NEQ {.} goto syntax
@echo REGEDIT4>"%TEMP%\RegisterPTFwrk.REG"
@echo [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\%ext%\PersistentHandler]>>"%TEMP%\RegisterPTFwrk.REG"
@echo @="{5e941d80-bf96-11cd-b579-08002b30bfeb}">>"%TEMP%\RegisterPTFwrk.REG"
:loop
shift
if {%1}=={} goto :done
set ext=%1
if {%ext:~0,1%} NEQ {.} goto syntax
@echo [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\%ext%\PersistentHandler]>>"%TEMP%\RegisterPTFwrk.REG"
@echo @="{5e941d80-bf96-11cd-b579-08002b30bfeb}">>"%TEMP%\RegisterPTFwrk.REG"
goto loop
:syntax
@echo Syntax: RegisterPTF .ex1 [.ex2] [.ex3] ... [.exn]&goto :EOF
endlocal
goto :EOF
:done
rem regedit /s "%TEMP%\RegisterPTFwrk.REG"
endlocal

I ran this batch with VFP extensions.
