So I downloaded some Sailboat mod from TES Nexus. I went to the marked location to find - an exclamation mark. So, what's the problem. I put the meshes/textures thingies in the data . Do I put them all together in the Oblivion mesh file?

Did you put the meshes/textures in the "data" folder, or in the "meshes"/"textures" subfolder in "data" (if it doesn't exist, create it)?

Oh, I just left them in their mesh file in which they were extracted. Should I put them all together?
