Several folders in the main game directory can be used as override folders. The following folders have this function, and are prioritised in the listed order:

1. Characters (overrides all others)
2. Portrait
3. Sounds
4. Scripts
5. Override (overridden by all others)

---

Enhanced Edition games support additional override folders located in the language or user profile directory:

1. home:/movies (overrides all others)
2. home:/characters
3. home:/portraits
4. home:/sounds
5. home:/scripts
6. home:/override
7. install:/lang/xx_YY/movies
8. install:/movies
9. install:/characters
10. install:/portraits
11. install:/lang/xx_YY/sounds
12. install:/sounds
13. install:/scripts
14. install:/override (overridden by all others)

Where install: indicates the installation folder and home: the user profile folder of the game. The lang folder used by the game is dictated by the current language.

Notes:
The game's profile folder name is defined by the entry "engine_name" in the file engine.lua, which can be found in the game's installation folder. It defaults to "Infinity Engine - Enhanced Edition" if the folder name has not been defined. Crash dump files will always be placed into that folder.
