For file type

Hi Sinusite,

You can use native file input with file field. It's the default browser file input, which allows us to select files from computer only.

Thanks for the error, I will check it.

The file field, of course, doesn't have good UI. I will search to see if the WordPress media can force users to select files from the computer. If there's a solution for that, I will add to the file_advanced field.
