New folder thumbnail is useless. in windows 10 folder icon I can see what file is on that folder sometime i don't have to check the folder because in thumbnail I can see the file image. but in windows 11, If my folder contain a file it just a white border at the top as a thumbnail. I think Microsoft should make a new folder icon which will allow to view the file from folder thumbnail or give some option to make this like windows 10 folder icon. Is there any way to do this now?
