why does the sims 2 needs and aspiration cheat delete things from game and computer?

boolProp testingCheatsEnabled [true/false]

Used by Maxis for testing certain aspects of the game. This cheat has many, MANY uses, not all of them useful for the player, and some of them potentially harmful. If you must use the testingCheatsEnabled cheat, only enable it for exactly as long as you need to use it, then turn it back off. You will likely experience errors if you leave this cheat on - the cheat itself does not cause errors, but shows you errors that were happening anyway. If you do get errors, click CANCEL or RESET on them.
