The users can control their own notifications in their settings.  There's no way (in default Elgg) to turn it off specifically for files, but you can turn it off for the group, or set it to send only site messages instead of email.

Hi

Where could I find the "turn off for group" settings, I can't find it

Cheers

You might want to comment on the specific plugin page.

Hint, the action also calls the elgg mail function for rejecting the profiles.

@everyone: I've deleted several abusive, off-topic, and unhelpful posts from above. Insults are never acceptable here; please just report them instead of engaging in tit-for-tat exchanges. When persons ask for help, please make genuinely helpful replies; snark to the effect of "learn to program" is not helpful. Please keep your arms and legs inside the cart until it comes to a complete stop. Please enjoy the rest of your weekend!

Thank you Steve!

Hope you have your answer Martin

Thank you gentlemen. 

Seemed to kick in when I logged back in, must have been the browser cache.

Language strings are also cached by the elgg system if you have caching enabled in your admin settings.  Use the flush-caches button on the admin widget to clear them when you make such changes.
