Trigger to detect change of filename

Is there any way a trigger could detect a change in an assets File Name details? 

 

We have authors who occasionally update document assets using a different filename. As we have many external sites referencing assets on our site (Unrestricted Access by default), I encourage authors to retain filename when updating assets to avoid breaking links from external sources when possible.

 

An Ideal situation would be a warning to appear (+ continue/cancel button) when an existing file asset is being updated with a file with an alternate filename.

 

Cheers for any help.

You can't really stop them from doing it, but should be able to set up a trigger that sends an email if someone does it. Probably use the asset attribute changed event and listen out for file name changes to file assets as the conditions.

Cheers Bart, I reckon that's a pretty graceful alternative.
