How to delete facial animations

[Kuriko]

Hi there. I just reinstalled skyrim and i remember i had deleted my facial expressions previously so i could create my own in screenshots but i forgot where and which files they are.

Depending on whether the facial animations are vanilla and/or who made them they are usually located in: Data/Meshes/Actors/Character/Animations/Female or Data/Meshes/Actors/Character/Animations/Male though a couple of modders have used their own unique file locations...
