@Sonshine That is not the path I was talking about. The path that you've shown in your post is where the game files are installed. NOT where the cache files are located. And no you don't want to delete the files that are installed in the Origin Games folder. As that will definitely mess things up.
Here's something that might help understand Sims a little better:
This is where your The Sims 4 folder is located:
C:\Users\<username>\Documents\Electronic Arts\The Sims 4
(game saves, cache files, option files etc.)
This is where your game files get installed by default
C:\Program Files (x86)\Origin Games\The Sims 4
Hopefully this makes more sense.

I dont' know about deleting cache files. I clicked on your link Mrs Flynn, and what I have doesn't even come close to what you list. I opened Program Files 86/Origin and every single sub folder in them contain .dll files. I do not want to delete those!
