More front page full width sections

I would like to add more front page full width sections, please.
I already tried, probably not very safely, and cannot find a way to delete the new files I have uploaded to the Theme Editor. It isn’t disrupting the site, luckily.
So this is essentially two questions:

  1. How do I delete a .php file I uploaded to the directory wrong? (Image attached)
  2. How do I add MORE front page full width sections?

Thank you in advance!

Hello there,

I hope you are doing well today.

  1. You would be able to delete the file by using the FTP that is provided b your hosting provider, simply access the FTP then navigate to the theme folder and there would be an option to delete the file.

  2. In order to add another widget section you would have to enlist the aid of a third party developer do so as it requires the theme to be changed to accommodate those changes.

Best Regards,
