I created an ESM/ESP/BSA I am calling Flora and Tree Models. It has become a lot more than just florae and trees. I want to rename it to something like Modders Resource Collection. But I already have quite a few mods (ESPs) that use it as a master. I tried renaming the three files and opening one of those ESPs, telling the CSE to also open the new ESM, but the new things were not loaded.

Is there a tool that lets one (such as me) do this?

THanks!
