You need Tank Creator to repackage the files after you've viewed/edited. I can't remember if I found it here on Nexus or by doing a web search, but it was pretty easy to get.
Tank creator can be found on https://www.siegetheday.org/, but it doesn't work. I think it doesnt work on windows 10 or later, not even in compatibility mode.

But how do I "repack" the extracted files?
