ZIP archives with an uppercase extension (*.ZIP) are not detected as such, and probably more #5

[Rackover]

Hello, I'm creating this issue as a follow up on issue itchio/boar#5 as it was apparently done inn the wrong repo.
Games I submit have an all caps naming convention, but itch launcher does not detect .ZIP as valid zip files - the handling is done depending on the extension and the extension is not lowercased before checking (or the check is case sensitive).

I got a comment 2 days ago on one of my games that this is still a problem. Is someone already looking into it or should I?

I've never touched go in my life but I can try, has someone a clue to where that check could be ran ? 🙂

Thanks, have a good day
