extract a specific file from zip directory

Folks

I have a batch that unpacks all files from a zipped file

@echo off

set SRC=C:\Daily\Received
set DEST=\\bp1xgbap670\Daily\Unpacked

for /f "tokens=1,2,3 delims=/" %%a in ('echo %DATE%') do set TODAY=%%a%%b%%c

REN "%SRC%\maximo.ear" "maximo.zip"

if not exist "%SRC%\maximo.zip" goto :NOFILE

REM -o is Destination folder
REM -p is Password to automatically enter - change this to suit
REM -y is option to accept all prompts

C:\Progra~1\7-Zip\7z.exe e -o"%DEST%\maximo" -y "%SRC%\maximo.zip"

7z e -o"%DEST%\maximo" -y "%SRC%\maximo.zip"

goto :END

:NOFILE
echo.
echo       Sorry, the file:
echo       %SRC%\maximo.zip
echo       Was not found.
echo.
echo       Press any key to quit ...
pause > nul

:END

but how to i only extract a file called "tester.jar" from maximo.zip?

all help will do

There does not appear to be a way to extract particular files using 7z.

The (ostensible) excuse is that "7z's default behavior is to create "solid" archives for better compression. It is impossible to extract single files from such archives."

Personally, I use plain old, free unzip.exe which will do what you want.

Available many places, for example:

this is easy with the command line pkunzip.exe utility

pkunzip "%SRC%\maximo.zip" -e <filename>

This would extract the specific filename from the zip.
