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

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

This is an update of the accepted answer to support filenames with spaces ("DELIMS=") and skip overwrite (-aos). See links below and updated code. Thanks
