What is a USM file?

USM files mostly belong to The Witcher 2: Assassins of Kings by CD PROJEKT. USM filename extension is used by video files containing game cutscenes and prerecorded action sequences. This file type is associated with Scaleform GFx, a middleware that allows developers to create video game user interfaces with Flash technology. Prerecorded action sequences and cutscenes used in video games that use Scaleform GFx are stored as videos in USM files. A USM video may be used to render intros, storyline, level completion replay etc in a game.

How do you open USM files?

You need a suitable software like The Witcher 2: Assassins of Kings from CD PROJEKT to open a USM file.

If you cannot open your USM file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a USM file directly in the browser:.
