Thanks, Jim! Great for #1. I should have known .
But for #2 (webarchives), I’m a little puzzled: I have a webarchive (in DT 3.7) whose correct URL is https://www.alamy.com. If I change the URL (in DT) to https://www.alamx.com (replace the final ‘y’ with an ‘x’) in Safari I get a 404 of course.
In DT I created a Smart Group (not necessary as I also do that in the Smart Rule itself) to look for any URLs containing ‘alamx’ (“Kind is Web Archive” + “URL contains alamx”).
Select the resulting item in the Info pane → right click → Apply Rules:
But nothing seems to happen.
I know the answer will be simple… .
