How to search installed content for poses?

How can I find certain CC so I can remove it from my game? Specifically, I installed some poses, and mostly that was fun. But I installed some CAS poses, and I guess the game uses those automatically/randomly so now "manage households" looks rather bizarre. I don't know which .package files contain the CAS poses, so I don't know what to delete. Is there some way to inspect package files, maybe from the command line, to see what kind of content they contain? I have over 2000 of them, so I'm hoping for something that doesn't require too many manual steps.
