Batch file to Extract a specific file from Zip folder and rename to include Zip name

Question

I have Approx 300 zip files that will all have a file called SP_OUT.db contained withing one of the folders in the zip. These folders themselves may or may not be be zipped. I want to unzipped the file SP_OUT.db and place in a new folder. However as all the files are the same name i want to rename them to include the name of the ZIP in which it came from.

For example

A11_21156_AHDW1_1.zip extract SP_OUT.db and rename it to A11_21156_AHDW1_1SP_OUT.db A06_21047_APERCLASH1_1.zip extract SP_OUT.db and rename it to A06_21047_APERCLASH1_1.db

Any help with this would be great.

Thanks

Answer 1

What OS are you using? It looks like there should be a way to do this if you don't mind installing the program 7zip. You could then incorporate a 7zip command like the one below to only extract the SP_OUT.db files.

7z e archive.zip -oc:\soft SP_OUT.db -r

extracts all SP_OUT.db files from archive archive.zip to c:\\soft folder

May need to try using the x argument instead of e

.

EDIT: Worked out a script to extract each file. However I havent worked out yet how to add the original zip name to the start of the extracted SP_OUT.db filename.

I've marked the place in the script below where you woudl need to do this, and added 'REN' (Rename) after it to change the name of the extracted file.

@ECHO off
TITLE All your SP_OUT.db are belong to us
SETLOCAL ENABLEDELAYEDEXPANSION

REM Set your working directories below.
set targetFile=SP_OUT.db
set sourceDir=%CD%\source
set outputDir=%CD%\output
set 7ziplocation=C:\Progra~1\7zip\7z.exe

:start
FOR /f "delims=" %%a IN ('dir/s/b/a-d "%sourcedir%\*.zip"') DO (
 %7ziplocation% e %%a -o%outputDir% SP_OUT.db -r
 CALL :process2 %%a
  )
GOTO :eof

:process2
SET "fdir=%1"
REM ********* %fdir% will be the full path including filename of original zip file.
REM ********* Work out how to get just zip file name and put save to variable here.
REN %outputDir%\SP_OUT.db %put_the_above_zip_name_here%_SP_OUT.db
GOTO :eof
