Re: All CC for Sims 4 wont work in game from the way file was saved?

There are several kinds of downloads.

• zip, rar and 7z: You need to open these with a program like winrar or 7zip and extract the content to your mods folder
• .package files: You don't need to open these. Just copy those to the mods folder as is
• ts4script: Also just copy these to the mods folder. For those you can't have more than one subfolder and you need to have script mods enabled in your game options

Also make sure you have mods enabled in your game options.
