Replacing items in a scene

Hey there,

I want to know if its possible to replace items within a scene just by replacing the file with the same name as the old one.

Like we have a scene full of 3D models and we want to change one set model that has been placed in multiple areas around the scene and without having to go find each on and replace it with a different model can we just put it in the folder of the model we want to replace and make it the same name and take the old one out?

Thanks for the help in advance!

if the models are prefabs you can change the mesh of the original prefab and all the copies should update with the new mesh.
