I am not convinced that those came from this end.
I’ve scanned all of my releases for the past 10 years and haven’t found a single one.
Although I’m not saying it’s impossible. I have worked on Windows machines once or twice (but let’s just keep that between you and me).
I added a note to my release workflow:
search / delete all
- php_errors.log
- .DS_Store
- ._.DS_Store
- desktop.ini
If those files did come from me, I promise you won’t see the again. 😉
