Как-то так:

Код:

@echo off
setlocal enableextensions enabledelayedexpansion

set sSourceFolder=C:\test\OUT

pushd "%sSourceFolder%" && (
	for /f "usebackq delims=" %%i in (
		`2^>nul dir /a:d /o:n /b "p00??." ^| findstr.exe /b /e /r /c:"p00[0-9][0-9]"`
	) do (
		echo [%%~i]
		pushd "%%~i" && (
			"C:\ARJ32\ARJ32.EXE" a "C:\TEST\IN\%%~i.ARJ" ""??.xml""
			popd
		) || (
			echo Can't set current directory to [%%~i]
		)
	)
	popd
) || (
	echo Can't find sorce folder [%sSourceFolder%].
	exit /b 1
)

endlocal
exit /b 0

fiksikyu,
а обязательно ARJ, если бы 7z (zip), то и одной строчки достаточно:

Код:

@echo off
set "d1=C:\TEST\OUT"
set "d2=C:\TEST\IN"

for /f "delims=" %%a in ('dir /ad/b/s "%d1%\p0*"') do 7z a "%d2%\%%~nxa.7z" "%%a\*"
pause
