Nested For commands in Batch File

Question

I'm trying to create a simple batch file that will individually compress "rar" each file in the source directory. Naming of the rar files should be based on the date/time of file creation.

Having difficulties getting the names to reflect the accurate date/time. Currently all rar files created bear the same name. Think problem has to do with the use of nested FOR commands

Newbie here. Would appreciate help if possible.

setlocal
set _source=H:\Test
set _dest=J:\output

for /f "delims=/ tokens=1-3" %%a in ("%DATE:~4%") do (
        for /f "delims=:. tokens=1-4" %%m in ("%TIME: =0%") do (
            set _FILENAME=basename%%c%%b%%a%%m%%n%%o%%p
        )
    )

ECHO %_FILENAME%

for %%I in (%_source%\*.*) DO (

md "%_dest%\%%~nI"
"rar.exe" A -v50M -m0 -k -y -ep1 -r -t -hp[aabbcc] "%_dest%\%%~nI\%_FILENAME%.rar" "%_source%\%%~nxI"
phpar2.exe c -s640000 -r10 -l "%_dest%\%%~nI\%_FILENAME%.par2" "%_dest%\%%~nI\%_FILENAME%*.rar"

)

@echo off
setlocal
set "_source=H:\Test"
set "_dest=J:\output"
setlocal enableDelayedExpansion

for %%I in (%_source%\*.*) DO (
    for /f "delims=/ tokens=1-3" %%a in ("%DATE:~4%") do (
        for /f "delims=:. tokens=1-4" %%m in ("!TIME: =0!") do (
            set _FILENAME=basename%%c%%b%%a%%m%%n%%o%%p
            ECHO !_FILENAME!
        )
    )
    md "%_dest%\%%~nI"
    "rar.exe" A -v50M -m0 -k -y -ep1 -r -t -hp[aabbcc] "%_dest%\%%~nI\!_FILENAME!.rar" "%_source%\%%~nxI"
     phpar2.exe c -s640000 -r10 -l "%_dest%\%%~nI\!_FILENAME!.par2" "%_dest%\%%~nI\!_FILENAME!*.rar"
)

endlocaL
endlocal

Is this what you want? You can nest the three loops but to use _FILENAME you'll need delayedExpansion.
