Pretty straightforward question, I hesitated posting this for fear I might be violating some rules, I just want to know, where I could find the store items in s3oc.

For example, if I wanted to clone and remesh or recolor a fence, where could I locate it for cloning?

Peter's tools do not offer direct facilities for pirating store items. However there are indirect routes people have discovered, which I am not going to describe here.

But Inge, it is not piracy, if you did buy the object in the Store and installed it with the launcher in your game, it will be included in the DCCache and the downloaded file in your Downloadsfolder.
I think she wants to know if it is possible and how to acces them, to make a clone or recolor for it.

It is piracy from the point of view that EA specifically made the store items encrypted to a different file format, with the intention of making them non-clonable. That is to say, their licence terms for store items can be assumed to forbid copying, and would certainly forbid copying and sharing with others.

It would be possible for Tammy Trauma to research a way round this, but probably not on this site.
