Anyway to tell Unity not to import a folder?

I have a folder in my Assets folder that I want Unity to not import the contents of, or atleast show the contents without converting it all. Is that possible?

No, anything thats in assets is under unitys control and meant to be. if its not meant to be used by unity, don’t put it in assets (there is no reason to have it there then as you obviously don’t want to interact with it in any form with unity measures)
