I'm hoping I'm posting this in the right place.

Is it possible to convert an .omod file back to the original .esp, and other standard files such as meshes, textures?

I've been searching the internet for how to do this, but what little I have found doesn't work- such as right clicking the .omod in the OBMM and file archive only reverts it back to the config file, and the other OMOD ready files.

Tried using right click and "Extract to folder" on the omod?
Desktop is a good folder choice as the omod is extracted to a folder named for it there.

I have Oblivion Mod Manager 1.1.12, which seems to do this quite well.
