The archive file is titled '6.30.1 + activator.rar' there should be no need to add any extensions.
Opening that with WinRAR should show 2 folders:
The first is '3GH activator' and the 2nd is 'Audi MMI 3G HDD 2020 6.30.1' which need extracting and copying onto SD cards.
Are you using a Mac? Can often cause issues with archive files created in Windows, as there's hidden system files that Mac doesn't deal with well.
If that's not what you're seeing, maybe someone can report that they've successfully downloaded and used the files, to confirm it's not an issue at my end?
Could always use the Mega link.....
