This action downloads, unpacks, and configures 7-Zip for use in GitHub Actions workflows. 7-Zip is a free and open-source file archiver. 7-Zip is unpacked under the temporary directory of a runner.

- uses: milliewalky/setup-7-zip@v1

This action appends 7-Zip to a temporary PATH file, so doing this:

7z a -t7z {dst}.7z {src}

Should do just fine.
