What is a UEXP file? A UEXP file is an asset export file created by Unreal Editor . It contains asset data associated with a corresponding .UASSET file, which contains the asset's file header . UEXP files are found in .PAK files that contain cooked Unreal Engine assets.

More Information A developer creating a video game with Unreal Editor can cook assets they're using in the game, which strips out some pre-processing data. When a developer does this, the asset is transformed from a single UASSET file into a set of three files: a UASSET file, a UEXP file, and a UBULK file. These files are often saved in a PAK archive. The UEXP file contains the data used to load and show the asset in-game. The UASSET file contains the asset's file header, and the UBULK file contains the asset's bulk data.
