I know how to delete apps using the finder method but what I don't find the easiest is deleting the files that aren't so obvious that are tied to that app. For example, I'm trying to delete Opera web browser. I go to finder > Opera > Show all in Finder > + > Kind > Other > System Files > are included A huge list of things come up, emails, messages, documents, style sheets, dat files and application. Other than deleting the obvious application, how do I figure out what other files are tied to it? Sometimes with other apps I'll see the name of the app somewhere in the name of that file but this time it's not so simple. Any advice?
