Extract then recompress a file in a zip archive

Hi,

I need to extract a file from zip archive, modify it then recompress it in the archive.

I saw the ZipDLL but it seems to be able to unzip files only.

Is there a way to do it with NSIS?

You could use the cli version shipped with 7zip (7z.exe) but this would increase the overhead for ca. 110 KB.

What is the cli version? What file in the 7-zip folder do I need?

He means the command line version of the 7-zip. You can download it separately here http://www.7-zip.org/download.html
But I am not so sure if it can pack zip files. 😕

7za does compress and uncompress Zip archives.
