Here's why:

* Paper is primarily made of cellulose fibers, which are organic materials and poor conductors of electricity.

* The folder might contain some metallic components, like staples or metal binding, which are conductive. However, these components are usually small and isolated, so they won't make the entire folder conductive.

Therefore, unless there are large metallic parts in the folder, it is safe to assume it is not a conductor of electricity.
