When is recursive packer being released?

In other news, I wrote (re-wrote) the same thing a few weekends ago. You need to download 7-zip command line, UPX, and OptiPNG. Modify the paths to the program files in the script below to what you have.

@echo off

:: Quick'n dirty solution to repack a JAR file with 7-Zip.
:: The JAR file itself will be overwritten with the new compressed JAR file.

:: 7zip executable existence check (set your path to 7z.exe here)
set _7zp="..\Tools\7-zip\7za.exe"
if not exist %_7zp% goto no7zp

:: temp directory existence check
set _tmp=%temp%
if not exist %_tmp% goto notemp

for /r %%e in (*.jar) do (if exist %_tmp%\%%~nxe (rd /q /s %_tmp%\%%~nxe) & md %_tmp%\%%~nxe) & (%_7zp% x %%e -o%_tmp%\%%~nxe\ & %_7zp% a -mx=9 -r -tzip %%e %_tmp%\%%~nxe\*.*) & (rd /q /s %_tmp%\%%~nxe)

goto end :: finished for now

:no7zp :: no 7-Zip executable found
echo 7zip executable (%_7zp%) not found & pause & goto end

:notemp :: no temp directory found
echo Temp directory (%_tmp%) not found. & pause & goto end

:end :: this is the end, my friend
set _7zp=
set _tmp=



:: Compress executables with UPX

set _upx="..\tools\upx\upx.exe"
for /r %%e in (*.exe,*.dll,*.sys,*.com,*.so,*.irc,*.pyd) do %_upx% "%%e" --best --compress-icons=0 --nrv2e --crp-ms=999999
set _upx=



:: Compress PNG files with OptiPNG

set _png="..\tools\optipng\optipng.exe"
for /r %%e in (*.png) do %_png% -o7 "%%e" 
set _png=
