Uasset file transfer

I’m trying to unzip a project so I can edit it on a new computer, but all the folders have Uasset files that disappear upon exporting. I’ve tried to drag and drop, and copy and paste to the content folder, but it just won’t work. When I drag and drop, it doesn’t recognize the file type, and when I copy and paste the Uassets to the content folder, it acts like it isn’t even there. These are specifically files containing A character controller, blackboard and behavior tree.
