The Sims 4 Folder Overview

When adding special content to your The sims 4 game, or if you downloaded a sim or house someone created, or if you want to play someone else’s save file, you need to add the files to the appropriate folders here.

To feel comfortable organizing your The Sims 4 folder, you should understand what all these different files do and which ones are needed to successfully add content created by the community sims 4 community.

All your important files are located in The Sims 4 root folder. By default, the file location for both PC and Mac is:

Documents > Electronic Arts > The Sims 4

the sims 4 folder

Tray files are where information about your plots, houses, rooms and sims are stored. If you downloaded a house or sim file that someone created, you should put those files there. If the home or sim you downloaded uses Custom Content and you do not have this Custom Content installed, they will not be visible or may look different. Typically, creators report it with the Abbreviation “NOCC” to indicate that there is no Custom Content in the build or sim.
