How do I convert my existing zip files to 7z with 7-zip comand line?

I'd like to convert a couple thousand zip files to 7z, with maximum compression and multithreading enabled.

Also in another place. Like c:\temp\file.zip to f:\converted\file.7z

You can use arepack (included in atool command suite) to convert between archive formats. Combined with a little bash, it makes easy to convert a bunch of ZIP files to 7z:

for f in *.zip; do arepack $f $f.7z; done
rm *.zip

Nevermind, does the job just fine!

Edit: But hell, it takes way too long....

I wrote a script in Python - You can run it with:

./zip27z.py your_archive.zip

and it will create your_archive.7z near it.

Or you can install it on your system with make install (if you see the repo)

And just call:

zip27z your_archive.zip

It needs unzip and 7za programs.

You can modify it as you wish for your needs (and send me a pull request)
