Somehow I've got two similar "Files" app installed. Since it is translated, I can't even identify the name to purge it. How do I leave Phanteon Files only?
They seems quite similar, but for sure is not the same app.
Pantheon-files by elementary LLC has a light-grey folder icon with a 'home' symbol on top of it. To uninstall its competitor ('Arquivos' app with a blue locker icon):
Go to AppCenter
> Installed
tab.
Scroll until you find Arquivos
app with a blue locker icon.
Click it and hit Uninstall
button.
