Hello there
For some reason I got 200 Materials in my architectural scene that pretend to be used somewhere, but I can not see them anywhere and I’m running out of video memory because of them. They also look pretty much the same. Is there a way to delete USED materials from my project or at least to identify the objects that are wearing them ?

Sweetheart, I wrote it in capital letters: I need to delete U S E D not unused materials 
But thanks for you effort 
If you have USED materials in the library, it is because they are applied somewhere. you cannot remove them, you need to apply something else instead.
Do a muti slection of the materials you want to remove in the material editor, and drag another material from the library on it (in one move). They will all be replaced by the DUMMY material
