Thanks for the response bcworkz,
The files are linked through the [google-drive-embed] shortcode for the link to the Google account, The files are then linked using the url=”” of the actual file. Not available as an attachment or post meta.
I’ll have a look around to see if I can find a plugin to do this, have been looking but so far had no luck.
The custom coding I think is beyond me for PHP as I do not know this language.
