A HUS embroidery file is a design file that was used throughout the 1990's created by Husqvarna-Viking, a Swedish company that creates sewing machines. Computerised embroidery machines such as this those made by this company have been in production since the early 1990's with support for a specialized memory card, floppy disk, and USB connections. The HUS format was replaced after a merger of the company with PFAFF in the late 1990s.
