What is an HHI file?
An HHI file is a data file used by The Sims 4, the fourth edition of the popular life simulation video game series. It stores game content about a household of one or more sims, which are people the user controls.
You will most likely encounter an HHI file only if you are looking to modify game content for The Sims 4. The file is part of a set of files that contain various information about a Sims 4 household. For example, a household with two sims consists of the following five files:
- 1 HHI file
- 1 .HOUSEHOLDBINARY file
- 1 TRAYITEM file
- 2 SGI files (each sim gets their own SGI file)
These files can be found in the Tray folder in the following directories:
- Windows XP - C:/Documents and Settings/[username]/My Documents/Electronic Arts/The Sims 4/
- Windows Vista, 7, 8, and 10 - C:/Users/[username]/Documents/Electronic Arts/The Sims 4/
- macOS - /Users/[username]/Documents/Electronic Arts/The Sims 4/
NOTE: You may also encounter HHI files when browsing files used by the Xbox One and PlayStation 4 versions of The Sims 4.
How to open an HHI file
To use an HHI file with The Sims 4, place it in the game's Tray folder along with the file's accompanying TRAYITEM, HOUSEHOLDBINARY, and SGI files. The content your files contain will then appear in the game.
