For interactive fiction, these files hold game data for the Glulx engine. They contain compiled story content and commands used by interpreters such as Glulxe, which is common in Inform 7 projects.
In other cases, a ULX file is a log container.
such files are built as ZIP archives and record data from systems like the Xam8000 ultrasound device.
