Windows Command Line – How to Extract All Zips in a Directory with a .bat File

7-zipbatch filecommand linewindows

I want to extract all .zip's and .rars in a folder and its children

The structure is like this:

MAIN_FOLDER
    -A folder
        - a.zip
            -a.rar
    -B folder
        - b.zip
            -b.rar
    -C folder
        ....    
            ...

I tried already this, which did not work

FOR /D /r %%F in ("*") DO (

  pushd %CD%
 cd %%F
    FOR %%X in (*.rar *.zip) DO (
        "C:\Program Files\7-zip\7z.exe" x %%X
    )
 popd

)

I use Windows and have 7-Zip installed.

Additional Question: Would it be possible to save all the extracted files from the last children (a.rar, b.rar) in one and the same folder (main folder)?

Best Answer

The Script:

for /F %%I IN ('dir /b /s *.zip *.rar') DO (
    "C:\Program Files\7-Zip\7z.exe" x -o"%%~dpI" "%%I"
)

Explanation:

for /F %%I IN ('dir /b /s *.zip *.rar') DO (

This performs a loop for each file returned by the command dir /b /s *.zip *.rar. The /s tells dir to recurse into subdirectories and /b prints in bare format.

The filename is stored in the %%I variable for use later. If you were typing this at the prompt, you would use %I instead.

"C:\Program Files\7-Zip\7z.exe" x -o"%%~dpI" "%%I"

This performs the extraction. The argument -o"%%~dpI" extracts the file into the same directory where the archive resides. Other options:

-o"%%~dpI" — Extracts into the directory where the archive resides.
-o"%%~dpnI" — Creates a new directory in the hierarchy named after the archive and extracts there (that is, AFolder\archive.zip extracts into AFolder\archive\).
-o"%%~nI" — Creates a new directory in the current directory named after the archive and extracts there (that is, AFolder\archive.zip extracts into .\archive\).
Omit the -o argument — Extracts into the current directory.

Example:

C:\Temp>tree /F

    Folder PATH listing
    Volume serial number is 08A4-22E0
    C:.
    │   batch.bat
    │
    ├───AFolder
    │       a.zip
    │
    ├───BFolder
    │       b.zip
    │
    └───CFolder
            c.zip



C:\Temp>batch.bat > nul


C:\Temp>tree /F

    Folder PATH listing
    Volume serial number is 08A4-22E0
    C:.
    │   batch.bat
    │
    ├───AFolder
    │       a.zip
    │       a.zip.txt
    │
    ├───BFolder
    │       b.zip
    │       b.zip.txt
    │
    └───CFolder
            c.zip
            c.zip.txt

Windows – How to extract all ZIP files in subfolders using 7-Zip on Windows 7

As far as I can tell, 7-zip doesn't have a command that does what you're looking for. Here's a Windows batch file script which I think will do what you want. It should be run from the command line so you can supply a path to the root of the folder tree to be processed.

File unzipper.bat

@echo off
setlocal
if "%1"=="" goto Usage

call :Get7zCmd
:: Recurse folder passed in as paramater
for /r %1 %%Z in (*.zip) do (
    echo ====
    rem Change to the directory of zip file
    cd /d "%%~dpZ"
    rem Extract all files to current directory
    echo %_7zCmd% e "%%~nxZ" -y
    rem Delete the zip file
    echo del "%%~nxZ"
)
goto End

:Usage
echo.
echo Parses through folder structure starting at the specified path, finding
echo and extracting the contents of all zip files found, and then deletes
echo the zip file.
echo.
echo Usage:
echo     %~n0 root-directory-path
echo.
echo     For example:
echo.
echo %~n0 "D:\some folder"

:End
goto :EOF

:: ==========================
:: Subroutine Get7zCmd
:: Determines the full path to 7-zip command-line executable from the Windows
:: Registry and sets the variable "_7zCmd" to the result.
:Get7zCmd
set Reg.Key=HKLM\Software\Microsoft\Windows\CurrentVersion\App Paths\7zFM.exe
set Reg.Val=Path
for /F "Tokens=2*" %%A in ('Reg Query "%Reg.Key%" /v "%Reg.Val%" ^| find /I "%Reg.Val%"') do call set PathDirectory=%%B
set _7zCmd="%PathDirectory%%\7z.exe"
exit /b 0

Since as a whole what the script does is fairly radical and potentially destructive because it might extract large numbers of file and delete many zip files afterward, I've disabled the commands on lines 12 and 14 which would do those things by prefixing them with echo. This make them just print out what they would have done if the echo wasn't there. That way you can test the script first without doing any damage to your file system should there be some sort of unexpected problem.

To modify the script actually perform these actions, you'll need to remove the echo on each of the two lines. Standard disclaimer of any liability applies, of course.
