About SharedPreferences in android

i was just wondering, if i wanted to reset the actual preference file used with SharedPreferences could i just rename the preference file ? , w开发者_如何学编程ouldn't that mean that the file still exist or does overwrite it ?

---

prefs.edit().clear().commit(); // prefs = SharedPreferences

is the proper way. Deleting the file with no referencing SharedPreferences objects should result the same.
