Extract all Zip's in a directory (incl. subfolders) with a .bat file or dos command

Question

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 7zip 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)?

thanks for your time

Answer 1

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

Answer 2

I believe that you are looking for the forfiles command:

• forfiles /s /m *.zip /c "7z x @file"

• forfiles /s /m *.rar /c "7z x @file"
