A simple question. I'm adding a custom field to a CPT to upload a file.
The file that needed to be uploaded are KML/KMZ files. Maps coordination files to show on top of Google Maps.

But I dont see any possibility to allow upload of those files.

I am missing something or how to do?

Hi, the default is based on WordPress's allowed mime types:

You can use the upload_mimes hook to add more mime types:

function my_custom_mime_types( $mimes ) {
    // New allowed mime types.
    $mimes['svg']  = 'image/svg+xml';
    $mimes['svgz'] = 'image/svg+xml';
    $mimes['doc']  = 'application/msword'; 
    // Optional. Remove a mime type.
    unset( $mimes['exe'] );
    return $mimes;
add_filter( 'upload_mimes', 'my_custom_mime_types' );

You can add the custom code to your child theme's functions.php file, or create a new custom code snippet in Toolset > Settings > Custom code. I'm not sure what the mime type definitions would be for those types of files, but you should be able to find out by searching Google.
