What is a UPROJECT file? A UPROJECT file is a project file created by Unreal Engine, a video game creation tool published by Epic Games. It is a text file that defines the project's basic settings, including the version of Unreal Engine with which the project is meant to be opened. Developers can open a UPROJECT file with Unreal Engine to edit or play the game the associated project contains.
