Some folders won't open, I think it's because they're old, right?

Nope. User issue.

@OfficalC11K 1. explain what "folders do not open" means.

Note: the compressed archives require the password "infected" and using 7zip to uncompress.

If you're still around, you can re-open the issue and clarify what you mean or show what error you get.
All the archives should be fine as they're compressed with modern 7-zip.
