extracting multiple files with 7zip & creating a folder for each

Question

I have like 300 zip files (but may get other kind of archives in the future) in a folder and I need to unzip each one in a subfolder of the archive name.

I've tried native 7zip options in command line but nothing worked yet, did not get any luck in the 7zip FAQ either. Finally tried "forfiles" in batch and that seemed to provide better results, but cannot manage to get it working.

Here is the last thing I tried :

forfiles /m *.zip /c "C:\tool\7-Zip\7z.exe e -o@path @file"

But cannot manage to get any result, this is what I get with a 4 zip sample:

C:\Users\tracto\test>forfiles /m *.zip /c "C:\tool\7-Zip\7z.exe e -o@path @file"

Answer 1

There is a built in command for this in 7zip.

This command line will extract all zip files in the current directory (e *.zip) to directories with names of archives (-o*).

 C:\tool\7-Zip\7z.exe e "*.zip" -o*

Ok in fact I've tried that before but it wasn't creating folders ... I've finally updated 7zip and ... well it worked that way, thx :) – Araucanian

works nicely, but can't manage to create a reg commande with it if you have any clue ... [HKEY_CLASSES_ROOT\Directory\shell\unziptofolders\command] @="cmd /c \"C:\\tool\\7-Zip\\7z.exe e %1*.zip -o*\"" – Araucanian

Try to redirect the output to a file by adding to see errors: >Log.txt. – Mopes

For those on Linux, I had to do: 7z e "*.zip" -o* (adding in the quotes). – Janeyjangle

you may also want to use the x flag instead of the e one, this will extract the archives by keeping the internal folder structure: 7z x "*.zip" -o* – Boettcher

Answer 2

In fact I did a batch that is getting called by registry :

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Directory\shell\unziptofolders]
"icon"="%SystemRoot%\\system32\\shell32.dll,45"
@="Unzip All"

[HKEY_CLASSES_ROOT\Directory\shell\unziptofolders\command]
@="cmd /min /c \"C:\\tool\\7-Zip\\7z-grpfolder.bat %1\""

with in that batch the following :

@echo off
cd %1
C:\tool\7-Zip\7z.exe e *.zip -o*

works like a charm.

Thanks a lot for your help !
