Update Service File: Used by UpgradeLauncher, this file stores update configuration data. It helps the system or application to manage upgrade parameters.

Game Data Archive: This variant keeps game assets and settings. Programs like BabyPark use it to package game-related data.

Ultrasound Image File: Following the DICOM standard, these files hold ultrasound imaging data used by medical imaging software.

Sound Bank File: Created for Sound Blaster 16 WaveStudio, it stores sound samples and configuration for audio playback. For more details, refer to the Creative support page.

FilExt.com note: The purpose of a US file depends on its source. Check file details or metadata to determine which software is needed to open it.
