Do you mean custom content? If so you may need a program called CEP FILES to make it show up in your game,Just download the program and install it as you would any other PC program.It is available via Mod The Sims 2 which is the place I linked to in my last post. You might also want to download and use another program called the Sims2Pack Clean Installer to install the files in your game.What I do with this is have a folder in my documents where I save all downloads,then when I have a few I right click on the folder and select the option "install all".It reads the files without even unzipping them and installs them in the correct place within the sims.
