Have have a similar question, probably about what needs to be edited in a file called SkyrimEditor.ini
It's in: Steam > Steamapps > common > Skyrim > SkyrimEditor.ini
If I understand correctly, in order for Enderal to run, it has to be named Skyrim.esm for Steam. So I don't think there is an Enderal.esm
BSA, ESM & ESP files are in the Data directory.
What needs to be put in the ini file & maybe others... Good question!
fwiw

Aside:
Just noticed the title next to my avatar.
"

Help!
