Find all scenes that have multiple files and remove the unecessary ones

[well-thats-funny]

In my collection, there's a lot of duplicated files, often of different quality (resolution, codec, ...). I've merged all such occurrences into single scenes, so now I have plenty of scenes that have 2 (sometimes 3) files associated with them. I'm looking for a way to remove all unnecessary files, leaving only the highest quality ones. Because of that, I've two questions:

1. Is there a way to find all scenes that have more than one file associated with them?
update: I found it, there's a "file count" filter

2. Is there a way to quickly go through them and remove all files besides the highest quality one? (so that I can avoid manually opening every one of them and manually compare parameters of the files)
