How do I unzip all files in a folder using 7-zip in batch?

Question

The title kind of says it all. I'm not sure how to do this, and the other post at Unzip all files in a folder using 7zip in CMD line

explains nothing to me very coherently. Could someone please help me with a simple way of unzipping all .zip files inside a specific folder?

Answer 1

This will unzip all zip files in the current folder(into the same folder), assuming you have installed 7zip into C:\Program Files\7-Zip location.

If you have added your 7zip folder into the path, you can just enter 7z instead of the fullpath

"C:\Program Files\7-Zip\7z.exe" e *.zip

Answer 2

Just to add up on Gabor's answer. My default installation folder was C:\Program Files (x86)\7-Zip so I'm going to go from there. Here is the link to download 7zip.

I wanted to unzip every zip file in a directory into multiple folder. however the e in the previous answer export everything in the directory.

Here is for the "normal" unzip creating a folder per zip file unzipped:

 "C:\Program Files (x86)\7-Zip\7z.exe" x *.zip

And to have a full details of what you can do with 7z.exe use the --help:

 "C:\Program Files (x86)\7-Zip\7z.exe" --help

Here is its output:
