You can delete everything in these folders, but not the folder themselves. You'll also see a folder titled cache and one titled cachestr. You can delete the localthumbscache.package file in this directory. To do this, go into Documents > Electronics Arts > The Sims 4 folder. It won't damage your save game, and this has actually fixed broken CC (particularly issues with script mods) for me in the past. The game will then repair itself and basically do a fresh install of the files needed to run The Sims 4. You can do this by clicking on The Sims 4 in your library, selecting the Settings button, and then clicking on Repair Game (please note that you must not be playing the game when you select this option). While you're online, go into Origin and repair your game.rar., or any other file type, they won't work in your game!
Remember, you should only see files ending in.
