Unlike in The Sims 3, where you actually had to add your Mods-folder on your own, the situation in Sims 4 is that with installing the game, this 'Mods'-folder will automatically be created by the installer. Package files need to be put into the following location: (My) Documents/Electronic Arts/The Sims 4/Mods.
These can include both 'mods' (CC that modify in-game mechanisms) and other general custom content like CAS items or buy-mode objects. Let's see.ġ) Virtually all third-party custom content (= 'user-made' stuff, if you wish) in The Sims 4 has the file format. But overall, this guide represents the status quo, at the time I'm writing this.
Keep in mind that the information presented here might become 'outdated' at some point in the future, and the guide itself may be edited, over time. I thought a *small* guide on custom content for The Sims 4 is in place.
