Make select file dialog for deleting duplicates wider

Feature Suggestions

I’m trying to clean my DB deleting movies that have several formats and keeping the one I like best.

But the issue is that the popup dialog that allows to select a file(s) to delete is very narrow and always cuts most of the file names, making it more difficult to know which one I want to delete.
Example:
Captura

This happens even though the window has plenty of space on both sides to show much more of it. Even if it doesn’t a horizontal scroll bar would be preferable.

And now that you are on it, how about adding some metadata to the dialog? (resolution, audio quality etc.)

Thanks in advance.
