If you are referring to poses that change the pose of the figure and not the textures, then there should only be files in the "Pose" folder.

However, if you are referring to the types of pose files called MAT POSE files that add textures to a figure, then there are files found in the Textures folder too, and sometimes the "Reflections" and sometimes "Materials".

What I tend to do when trying to delete or sort out files that I have lumped together is to dig out the original zip or .exe and unzip or install it to a folder on my desktop, and then look through it at the same time as I look through the runtime to find the files. That way I don't go wrong :)

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
