First, you can reset the gameplay folder to delete all cache items:
1. Move (not copy) Saves, Tray, Mods, Screenshots, and Custom Music folders and the Options.ini file to your desktop. Delete the Scratch subfolder from inside Saves.
2. Delete the rest of the The Sims 4 folder from your Documents > Electronic Arts folder.
3. Start the game, and exit the game. Now you have a fresh Documents > Electronic Arts > The Sims 4 folder.
4. Copy all the folders and the file back and start the game again.
I move my screenshots and videos to a different drive periodically, since I don't use them in-game. I also do that sometimes with older saves that I suspect I won't come back to.
