you first need an "installation" script :
@echo off
rem :: A files with .TEST extension will be able to execute batch code but is not perfect as the %0 argument is lost
rem :: "installing" a caller.
if not exist "c:\caller.bat" (
echo @echo off
echo copy "%%~nx1" "%%temp%%\%%~nx1.bat" /Y ^>nul
echo "%%temp%%\%%~nx1.bat" %%*
) > c:\caller.bat
rem :: associating file extension
assoc .test=batps
ftype batps=c:\caller "%%1" %*
then try a simple .test
file:
@echo off
for /l (1;1;10) do (
echo testing .TEST extension
)
In fact ASSOC
and FTYPE
both have immediate effect so you can start a .test
file right after "installation". With direct editing of the registry eventually you can get more control -> How to create file extension that behaves as .cmd/.bat? . Check also drop handlers -> http://msdn.microsoft.com/en-us/library/windows/desktop/cc144165%28v=vs.85%29.aspx
