Can we use UASSET file directly from my previous project to new project? or we have to export it from unreal engine

for example i have a uasset file of a glass material in file explore where my old project is saved so can i copy that to my new project?

I’ve copied sounds from an old project to a new project by copying the uasset file from the old project and pasting it into the content folder of the new project. I’ve not had any issues doing this.
